I had a P0306 (cylinder 6 misfire) that was driving me crazy! Just watched your video about checking for bent pins in the spider injector plug. Well guess what? I had one bent pin on the number 6 cylinder and I GENTLY straightened it with needle nosed pliers. Runs SMOOTH now. No more misfire. Thank you for sharing this information. Saved me a bunch of headaches not to mention $$$.
Life Saver- replaced spider injectors on 97 this last weekend - bent the pin for cylinder #1 - if I wouldn't have come across your vid - I would probably still be hunting
Thank you for your video I just put a new spider injection in in my 99 suburban and after I got it all together it ran like crap I hated the thought of having to pull it back apart and like yours I had a missfire in cylinder 8 ,we pulled the plug off after I had ran across your video and Shure enough the was a bent pin so thank vary much ....
I’ve installed new spider injector and notice a miss fire after installed. I’ve done everything plugs and wires, intake gaskets. Coil ,distributor. Maf sensor and map sensor. After watching your video it was a bent pin on the number 2 cylinder just like yours was bent I bent it back now it runs like new. You save me a lot of more headache. Thanks and god bless you.
Awesome your welcome, them pins are notorious for bending. I honestly don't see how they get bent so easily when your ever so gentle on pluging it in. Some soft metal 🤣 least it's a easy fix. Got to love chevy an them spider injectors. Lol
THANK YOU FOR POSTING THIS VIDEO. I have been working on my 99 Tahoe for days and couldn’t solve the issue. I have no idea how I did it but I had the EXACT same pin bend. Straightened it and now it runs great. Without your video, doubt I would have figured it out. What a coincidence that 2 people would happen to do the same thing. Thanks again!
One other thing these voctec motors will do. Intake manifold gaskets will sag on the plastic ones and cause a misfire. Replace them with the upgraded felpro gaskets. It is metal with rubber. Had to do it on my 99 Surburban.
Thank you!! Just finished replacing spider injector on 1999 suburban . Code p0301 for cylinder 1 misfire came up . Took off the connection for injectors and sure enough I bent a pin.
I had the same problem! I watched your video and realized I never checked that plug went back and BOOM there was 2 bent prongs! I’ve been hunting for a solution for 4 days! Thank you for making this video!
Hey man I was pulling my hair out pissed off till you said to check the spider injectors wiring harness. I had a cyc 6 misfire. The pin was bent. Man thank you.
I replaced the spider injectors on my 98 Silverado 5.7 about 7 yrs ago. After I put it back together, I had the same problem. As I was taking it back apart, I also noticed one of those prongs were bent. After straightening it out and putting everything back together, it fixed it... I guess initially, I got in a hurry and bent it when I first put it back together. Learned to slow down.
I have a 1999 k1500 suburban with a 5.7 thats is miss firing on 7 and I've had the whole injector housing replaced, but it's still there but clears up when I hit 70 mph, then when I shut it off it miss fires again.
May check to be sure the pin on the spider injector isnt bent if not, make sure you are getting spark to that cylinder from the plugs. Make sure plug wires has a good solid connection. Could also check to be sure that injector on that cylinder is spraying good an not clogging up. Check for corrosion to the harness to the spider. Last but least compression Check on that cylinder or could do that first.. If everything checks out to be ok may have something going on with the computer. Hope this helps
@@halomasterhalo1702 may also check cap, an button something may be wrong with the ignition system. Or like I said dealing with fuel only not enough fuel going to that cylinder.. Hopefully its a easy fix an not something internal. Which is the other reason I mentioned a compression check of that cylinder. Gives a few things to check on. And you are very welcome.
What does the tickingmean my 1999 tick Abit on the right side.the oil pressure gauge is cool.but I do here some ticking on that right side.is that normal this is my first v8 chevy.it runs great.
If your chasing a misfire on a 5.7 vortex after having your head replaced especially if it's a 1996 model for cracking make sure that they are truck heads and not Suburban if they are Suburbans they take a different spark plug made by AC Delco I believe it's an RT 41. I chased a damn obscure Miss in mind for the better part of six months and just out of frustration I threw these plugs in it and Bing Bang Boom the damn Miss fire is gone finally.
No lights prior to tune up new plugs, wires, cap an rotor shortly after light came on then off then on an off, an back on again. Basically it has a mind of its own I think it likes screwing with my mind. At first it only came on with a/c on or so I thought. At first it said change the 02 sensor did didn't turn light off. Then po300 code MULTIPLE misfire not random don't know if there's a difference between the two. Changed the cap unhooked battery and light stayed off for about 150 miles. On then off and back on again. All I know is when light is on mpg is way worse than normal and with gas prices almost $5 a gallon in CA these days I am basically working to pay for my gas to get to work. Any info would be greatly appreciated. Its a 1996 k2500 153,000 miles.
May help to check a few things here. May run a compression check on each cylinder an write down the compression. See if any of them hold compression for at least 1 hr doing this your just seeing if it dropped in compression.
@@amberericjones5694 whats crazy is I had no check engine until I put new plugs. I was reading somewhere on here iridium plugs, not platinum.. I didn't even know iridium was a thing smh learn something new every day. Could that be the problem? Idk know but when the light is off it runs great but out of nowhere the light returns and I can literally watch my gas gauge dwindle down instantly
@@blayzer2889 I know most vehicles are picky on which plugs it wants to run. But that's strange may try different plugs or find what is the oem plug thats supposed to be used from factory
LOL! I bent #3 swapping out MFI injectors. Runs like a beast now! Thanks for the video. Your fingers and tools can get in there; not protected pins at all. Pins are easily bent. Check all before connecting. Seat the connector by keeping it parallel the whole time. Can be tricky but a must!
May want to add some power steering fluid. Just saying 🤣 🤣 Thanks for the video. Mines doing the same and will check that out. About to lose my sanity and 2500 dollars later.
should drain the oil immediately after doing intake gasket in case antifreeze got into the oil- or at least crack the drain plug to drain antifreeze off the bottom of the oil pan before you start it
i have to do this soon i have a cylinder 3 misfire . i've did the sparks , wires, cap, rotor , ran a can of sea-foam thru her and still have the misfire .
@@MrBillybathgate5 yes you'll have to replace the whole spider. Be careful with the plug on the new one cause they are so easy to bend. If one of the prongs bend on the new. It will also throw a misfire code. If for some reason all is well with the injectors an you still throw a misfire code on 3 check the compression. Which that would be the first thing id check an should have done on this truck. Its easy an simple. If all compression is to spec. Then the injectors would be the thing id replace.
I have a 98 Chevy Silverado 3500 5.7 Engine, I have changed plugs , wires, and distributor cab and button and still can’t figure out the misfire please help
@@amberericjones5694 misfire is only at idle 🤣 at 2k rpm it goes back to smooth. I have a new complete distributor to install. Just waiting for motor to cool down.
@@amberericjones5694 well I have to repull the distributor and set timing. Chevy decided to move the rotor scew mount locations on the updated distributor.....put the old one in with a new cap and I'm 2 teeth off timing. Ugh
Hell yea imma check mine tomorrow no service engine light before spider replacement but after I put my new spider it ran better but stumbling sometimes with light on great video sir I’d give ya 10 👍 if I could!!
I had to take my 96 Chevy C 2500 2 wheel drive 5.7 l into the shop because both hands were cracked on a truck that never got hot. Replace both heads they did a great job. Got the truck back and I have a miss or stumble under load going down the highway but the truck idle fine. Cleaned and checked and verified the EGR is working properly checked all the spark plugs and recap them replace the cap and rotor and it is installed properly I don't know what the hell to do it's driving me crazy and I don't have a code in the computer they've even hook the big computer up and we drove around and the computer computer shows no problem through the driving range. It's driving me personally crazy
Have you doubled checked to make sure the plug wires are in the correct location from the plugs to the cap? I know sometimes getting them in the wrong location will cause a misfire or stumble may also check to see if your getting spark to all 8 cylinders. Also the injectors possible they could have accidentally bent one of the prongs on the spider injector. If all is good check compression or check to see if one of the injectors isnt spraying.
@@amberericjones5694 we think alike. That is exactly what I was thinking about the spiders that instead of putting that sweeping Bend IN for number one number 2 and 7 and 8 cylinder they somehow kinked or got it wrong they reused the spiders that were originally on the truck. They had been replaced about five years before I got the pickup. The truck idles perfect. It's only one I put it under load that it starts cutting out or missing if you will. El spark plug wires are pretty straightforward yes I have check them. I have not checked each cylinder for spark I'll get better go tomorrow. If this was an Evinrude or Johnson motor I would already had this figured out. Another thing that is stumping me is I do not have one code on the computer and the light works I've checked that first to make sure that the light wouldn't burn out and my PCM was full of a bunch of codes. LOL I certainly appreciate you getting back to me so fast most people in this world don't give a damn about anyone else.
@@brt-jn7kg almost sounds like fuel may be a bent pin on the injectors possibly. If it Only does it underload good possible. An ya you got that right most people dont. I try my best to reply back to people on here as much as I can. Love helping people out with some of their auto needs lol. I try my best lol
i have a 99 suburban 120k miles. replace cap and rotor, fuel pump and gas tank (it was rotted), spider injectors, spark plugs and wires, new ignition switch and relay, new maf sensor, intake. and when the truck is cold it runs fine as soon as it gets hot it starts to sputter a little bit when stopped. when you punch the gas to the floor it just bogs and doesnt want to get out of its own way. i have put 92 octane with booster in to try and clear up anything no luck. i was thinking a cat could be clogged. i get a code of o2 sensors possibly because cat is clogged? never got around to removing them and starting it up to see if that is the problem since the front 2 are before the cat. i also didnt put a stock fuel pump in and also thinking that could be a possibility. any input from anyone would be great thanks!
only thing i can think of is the distributor drive gear could be worn and slipping or my cats are clogged. thats my to do list but input would be great
@@raybanz6686 sounds like cats. If you got a temperature reading gun. You can let the vehicle warm up to operating temp. Take a reading before the cat and after. If the readings are different possible cats are clogged. If they reading the same may just be 02 sensors acting up. Another way you can drill a small hole in the cats an see if there is any restriction from the front of them to the back. So basically you would need to drill a hole in the exhaust in front of the cat check air flow. Then plug that hole an drill one to the rear exhaust behind the cat an check that air flow if the airflow is restricted. Then you have clogged cats. Couple ways to test it.
@@raybanz6686 also May want to check for slack in the chain too. Just throwing that out there. But if its feeling like your not getting enough back pressure or air flow out the exhaust possible clogged cat. But yea I would do that test and see first as I mentioned. May check fuel pressure, compression, etc.
Hi there i have a 1999 chevy suburban c1500 LT. When i turn on my vehicle the windshield wipers starts to going and it's on the off position. How do i fix it and my head lights won't turn on also.
Windshield wipers : check wiring could be a faulty switch at the column... loose or bad ground check fuses. Or possibly faulty windshield wiper motor. Be my guess
I have a 99 suburban with 322764 miles on it and she is still running strong I'm the original owner I wouldn't trade this truck for nothing Chevy really needs to stop take a look at the old school Chevys and find their roots again because these new Chevys have nothing
I've got a 97 ranger 2nd owner. My dad had it brand new off the dealer lot. I've turned every nut an bolt on the truck just about. I've rebuilt the engine, new clutch, rearends been rebuilt, from brakes to rear brake lines, wheel bearings, truck still looks good for its age besides the few dings an dents here an there. Other than that paint still holding like a champ. I'll never sell it it'll be with me till my dying day
I'm having mis fires after my spider injector conversion. 1999 Suburban. Engine has no power. Does not down shift. What price you pay for your injectors. Mine came from China at $179. I dont think the spider injector is up all the way in the manafold as the top plug does not seat down all the way. Meaning the two clips on the side dont mate properly. And does that white plug go anywhere? Seems to be just plastic.
Repull the connector you may have some pins that may got bent not allowing it to completely sit down. My price will be different than others ppls being I get a complete discount on parts.
@@amberericjones5694 I just check and they straight. Going to wait for a code checker to com in the mail. I know Auto Zone has one, but they wont clear the codes. Suburban ran alright before this, but recently it failed to start due to no fuel pressure. So I got a fuel pump ready to go in also. Fuel pressure jumps to 60 psi, but falls to 45 psi while running. Could be that too.
@@rogermerritt6470 fuel pressure seems alright does it hold fuel pressure with it not running if it holds fuel pressure for at least a hr not running at 60 psi that's good. With it running with fuel pressure at 45 that's not to bad. That's about right.
@@amberericjones5694 It goes down in half an hour. I decided to do the fuel pump also since the fuel gage never goes down beyond half way. I rely on the trip meter. So I clear trip meter when refueling and watch for when it gets down to about 300 to refuel. Have run iot down completly and saw that when it was bone dry the fuel gage shot down to zero fuel level. Getting 10 mpg in town. Terrible. In process of refueling wife's car with my gas since I had just filled the Suburban just before it started acting up.
I replaced all the plugs and all the wires and it started throwing a random misfire. I replaced the distributor cap and rotor and it’s still missing. I didn’t delete the old code
Be sure all your wires are hooked up right. Some gets them mixed up. Or unless something isn't connected good. Check to see if your getting spark on all cylinders have to pull them 1 at a time to check
@@amberericjones5694 fuses are good,relays are good,i dont know what wires to test with the meter,I put a new brake switch on where the pedal is and a new rear wire harness,Still none of the three work in the back

I have a problem, these guys put a new header on my 99 gmc 3500 and re did the gaskets and distributor cap, spark plug wires and plugs and now it idles weird and is choppy, when backing up with out putting the gas on it almost stalls ( it is an automatic 7.4 engine 454) any ideas?
Lucky you, simple fix. I did the same injectors on my 98 Tahoe, i was driving one day and bam started to mis, bog, lose power, check engine light came on. Code p0300 and the MAF sensor code. Replaced the maf sensor, still misfire. So i had a shop do a diagnostic test, and he determined it was the fuel injection. I ended up doing it myself because i didn't have the $850 to pay😏. So i got everything installed, new injectors, fuel filter. Plugs cap and rotor look ok. Started it up, seemed like it ran good for like a minute or so till it started to misfire again like i never did anything to it. 😫 it has about 198K miles on it. I was looking online and seems like these distributors go out? Idk anyway, these the story of my life. Lol
Jaime G. Yea, this truck did the same thing after I finished it up started with the b.s misfire again. Only code besides the abs sensor. Either distributor or the computer it's self because one minute it would throw a code and idle like crap next minute code would go off and idle perfectly. Owner didn't want to put no more money into the truck so he picked it up a while back.. I would replace the distributor and see if that don't solve the issue.
Jaime G. If you do the distributor, make sure that you are tdc compression stroke. You can put your finger over the #1 plug hole and have a friend bump the key over. After removing the coil pack to keep It from starting. Or rotate by hand. Mark your where your rotor is facing which should be facing driver side #1 cylinder. Mark the position of the distributor. Pull it and the new distributor should drop in. Make sure you put engine assembly Lube on the splines of the bottom gear.
Flywheel split and jumped time on a 96 suburban 4x4. Replaced both. 5&7 misfire. Only code is p1345. Replaced distributor. No change. Swapped engine. 146k truck engine. Drive it in to pull motor so I know it doesn't miss or have compression problems. Get it all together using suburban intake. Guess what!?! 5&7 show 90 misfires in less than a minute and the same code is back. I have spark. I have compression. Help!!!
What about the injectors? If no the injectors see what compression all the cylinders are at. If cylinder 3 is the lowest on compression an the rest are pretty high then you have something either going wrong with piston rings or other components internally
I did change the spider and thats when the misfire code came up I took it out and put a new regulator on the original and clean it up and put all the injectors in the right cylinders still have the 303 code I dont understand it I had the truck for months no misfire code
Can u help me. Having a misfire on cylinder 2. I have already changed coil plugs wires distributor the cap rotor still having the same misfire number two could it also be the Spider injector on my 96 2500
Take one of the coils swap them see if it changes... if not check to see if your getting spark to the plug. If you are. Check the spider Injectors see if that cylinder is spraying. You could have a weak spray on that cylinder or low compression... also check the pins going to the spyder make sure non are bent.
@@amberericjones5694 appreciate that very much! Don't Have individual coils. 5.7 vortec. Did change the one coil though. Afraid of the no compression bc of what I heard possibly having to pull motor to change rings..is this true. Very costly. Rather it be 🕷 injector though its a little work, i can do it myself.
@@creationzthruair834 hoping it's something simple like a vac leak or intake leak or even a injector... if you do a compression test on all the cylinders an say #2 shows really low compared to the other 7 cylinders.. yes motor has to be pulled torn down an new ring's installed. Which will need to be rebuilt.. sometimes rebuilding one is cheaper than buying new.. if it's not ring issues a simple head gasket issue can cause a cylinder to misfire. It can create just enough air leak. To find our you'll need a compression test done. If it jumps let's say up to 210 psi let it sit for a little bit give it about 1hr come back see if the compression has changed if it has dropped a significant amount say down to 200 psi you have a leak somewhere in that cylinder either rings valve seals etc... you then can also perform a leak down test with a fog machine and what it will do is let you see of you have any Intake leaks it may also pick up head gasket leaks too if any.
@@amberericjones5694 thanks . appreciate your time. Interested in the fog machine test..... Interesting. Gonna look into that. Never heard of it. I paint.lol.. mechanically inclined.yes, just dont know whole lot. So thank you again!!!!!
I have a 98 Suburban 5.7 with 216k miles. It idles well, but has a misfire on one cylinder only under load, worse when engine is cold. Only one day after running injector cleaner and running it hard, it ran perfect. then next day misfire was back. I have replaced the plugs, wires, cap, and rotor. My guess is clogged spider injector. Do you think it'd be worth it to try having the injectors cleaned? ($100) Or should I just replace the whole assembly?
@@camarokurt you can try to clean them first. But while your there may just wanna replace them. Also you may want to get a compression tester and just see what the compression is on all 8 cylinders... Because too low of compression will cause misfire an also hesitate under load.. But if youve ran fuel injector cleaner in it an seen a improvement more than likely fuel injectors are probably getting clogged up.
@@camarokurt Also wouldnt hurt to do the fuel filter the same time as the spider injectors. Because any trash that may be left in the system may clog the new injectors. Just a quick thought
@@amberericjones5694 its a 250k miles truck. Nothings seens to have been replaced in at least 4 years. Old guy used to own it. I dont even know where the start. Also smells like gas. I saw the canister missing a line.
So we have a 97 chevy that misfires when driving and it seems like it does not have full power until it accelerate on its own. We replaced spiders, wires, plugs and fuel pump and fuel filter but we still have a rough idle can anyone help ?
@@Malikamos1 do a compression test on all the cylinders. Be sure that all cylinders are running very close to the same psi. Lets say for instance cylinder 1 is 285psi cylinder 2 is at 280 that is fine that means their running really close to the same numbers cylinder 3 285 cylinder 4 is at 165 cylinder 5 270 cylinder 6 270 cylinder 8 274 cylinder 9 270. If they are reading close together or right around the same but 1 or more is showing way low. It is a good possible could have a stuck valve, bad piston rings on that cylinder or a valve seal/seat leaking. But usually that one will result in smoke an is very noticable on start up then goes away after its warmed up... But other option is either failing piston rings stuck valve etc.
@@Malikamos1 also may want to be sure that you dont have a pin on cylinder 4 injector bent. If So that will also cause a misfire. Double check your pins first then go through with the compression test.

@@jm1662 oooof, the only downfall is making sure you have proper torque an criss cross pattern. Wrong torque to tight or to loose pan will leak. Oil pans are simple but I hate doing them. Usually I like putting on a brand new pan being alot of time the pan is slightly warped when removed. Every one that I've deck checked has a slight Bend to it. An just that tiny bit of clearance will cause a leak.
@@jm1662 if the bolt didn't break off flush to the block you'll be able to remove it but if it broke off flush may have to weld a nut on sometimes this works sometimes not so much or drill an re thread tap it's a nightmare when they break off. 😬
Yeah it broke off flush... Nothing to weld to. Bro read the specs incorrectly 😕 up til that point everything was perfect..timing cover, all the top side gaskets... Then the last attempt when i finally got the pan off... Fugging drill bit broke off inside the broken bolt ....was able to drill a good bit out and rethread it but noy quite deep enough, and didnt do a good job putting it back together.

Actually, the one that he showed in the video, as the old unit, is an updated one, already!! There were some older units still out there, when some of these went bad, and needed to be replaced. But that one he replaced, was the updated version, of the mpfi spider!
I have literally replaced everything all new sensors and injectors new timing chain distributor wires plugs o2 sensors everything you can think of minus the pcm. And I keep getting p0300 and p0102 and open circuit for right abs sensor. I’ve checked the wiring harness and can’t find anything super annoying literally spent so much money. Super weird when drive at highway speeds 65-70 it will start miss firing and after driving and I put it in park it will idle super low and try to shut off. Also when I put my turn signal and try to accelerate it hesitates and starts bucking super weird.
@@amberericjones5694 yes I’ve changed the fuel pump twice just to make sure it wasn’t bad also changed the fuel filter and the fuel regulator. Engine runs super good just acts weird at times and can’t figure it out . You know the weird part is the p0102 won’t clear at times along with the abs code.
Informative video but as a skilled mechanic,why would you start the vehicle without putting oil in the power steering first!?! You risk burning up the pump with no oil!
Pwr steering pump was already going out I mentioned it to the customer to replace it but he didn't want put more money into it. But I did put pwr steering fluid in it after wards I didn't run it that long just enough to show everyone that misfire was solved. But no, pwr steering pump was already going out the door anyhow. Trucks used as a deer hunting truck anyhow. And by the way his father got him a new vehicle now this vehicle just sits not being used 🤣
Now if he had me replace it I would of turned the wheels lock to lock before starting the vehicle to bleed air out of the system. And would have made a full on video on how to do that. So hopefully that clears the air
I thought that might of been the case but you have to cover your bases knowing better that any pump or motor operateting without oil is going to be at risk of damage! I was trying to be helpful bro,any loved the video learned something new! Keep um coming! P. S.- this is the first thing I have ever remembered liking, subscribing and commenting on! Stay blessed!👍
@wallcottmoss3028 always man yea I wouldn't do that to a good pwr steering pump if that was the case. Your good man. I need to get back on here more been on tik tok more with all my mechanic vids. Most of the stuff I'm doing someone out there has already covered it.
Maybe all talk but I'm explaining a misfire problem that can be fixed if somebody is changing out a spider injector on these engines. Thanks for watching.
@Ed Al thank you for watching, I'll keep explaining for those that wants to learn something. You keep watching those videos that don't talk at all and don't explain nothing. Have a nice day.
@Ed Al if you paid attention I would have made a video on how to do the spider injector on this truck. But I was in a rush to get it done. So I made a video explaining the issue and how I fixed it. To help those that may run into the same issue. Take me with a grain of salt if you already know how to fix something no need to watch these videos. If not shut the hell up and pay attention you might learn something
Sounds like “saved by grace through faith” could reciprocate that grace given you explained you wish you had done a video on changing out the spider injectors. Thanks for sharing what you found.
I think chevys the only truck that the tail gate handle breaks 🤣 electrical issues, tyranny issues, drive shaft falls out, dashes all plastic and breaks under minimal pressure, fuel gauge issues and the list goes on 🤣🤣🤣
@@amberericjones5694 agreed, they all have the same exact damn problems. Design failures in my opinion. But they do have a reputation for having a strong engine.
@@roostercogburn2365 like I try to tell ppl including my own friends. Chevy did wonders for their engines. They put more thought process for hp and reliability. But they skipped out on everything else. Now, if they would have put that same thought process in hp and reliability as they would of the entire truck or car they would of probably beat Ford in the long shot... thing with Ford they built their vehicles to work hard they put the thought process in everything in certain vehicles. Not going to say all because they have some that are trash like the f150 and their 5.4 triton engines.. but as far as it being used as a work truck like when they put the thought in the Ranger they topped it...
They made those rangers indestructible damn near. I still have mine and still looks just as good. The other thing chevy cheaped out on is their paint. If you compare a chevy to a box car. It's like putting in a 454 in a box and driving it. Lol although ford did also build performance as well they also didn't skip leg day 🤣

Awesome your welcome, them pins are notorious for bending. I honestly don't see how they get bent so easily when your ever so gentle on pluging it in. Some soft metal 🤣 least it's a easy fix. Got to love chevy an them spider injectors. Lol
THANK YOU FOR POSTING THIS VIDEO. I have been working on my 99 Tahoe for days and couldn’t solve the issue. I have no idea how I did it but I had the EXACT same pin bend. Straightened it and now it runs great. Without your video, doubt I would have figured it out. What a coincidence that 2 people would happen to do the same thing. Thanks again!
Your welcome Jeremy jenks
maybe i need to pull mines apart . i might have same problem
Yep I was in the same boat same prong and everything can’t believe it
Nice clean engine compartment. Well done, sir.
Camper Pod Thank you sir
One other thing these voctec motors will do. Intake manifold gaskets will sag on the plastic ones and cause a misfire. Replace them with the upgraded felpro gaskets. It is metal with rubber. Had to do it on my 99 Surburban.
this video just saved my misfire code, couldn't figure it out for days one of the pins must have not been making contact, the truck runs smooth.
Those pins get bent easily.
Thank you!! Just finished replacing spider injector on 1999 suburban . Code p0301 for cylinder 1 misfire came up . Took off the connection for injectors and sure enough I bent a pin.
Yep.. me too 97 tahoe.. cyl 8 also... use tube of ink pen to straighten out and put back together with dielectric grease..
I had the same problem! I watched your video and realized I never checked that plug went back and BOOM there was 2 bent prongs! I’ve been hunting for a solution for 4 days! Thank you for making this video!
Your welcome, thank you for watching, subscribe
Hey man I was pulling my hair out pissed off till you said to check the spider injectors wiring harness. I had a cyc 6 misfire. The pin was bent. Man thank you.
Your welcome
Dude thank u so much. My new book shal be called one prong one week. Took me a week to fix what u just showed. Thank u so so much again. Gotta love it
I replaced the spider injectors on my 98 Silverado 5.7 about 7 yrs ago. After I put it back together, I had the same problem. As I was taking it back apart, I also noticed one of those prongs were bent. After straightening it out and putting everything back together, it fixed it... I guess initially, I got in a hurry and bent it when I first put it back together. Learned to slow down.
The AVS does that make a ticking sound when it's going out when you're driving low speed
That’s funny I had the same exact problem when I did the top end on my truck
I have a 1999 k1500 suburban with a 5.7 thats is miss firing on 7 and I've had the whole injector housing replaced, but it's still there but clears up when I hit 70 mph, then when I shut it off it miss fires again.
May check to be sure the pin on the spider injector isnt bent if not, make sure you are getting spark to that cylinder from the plugs. Make sure plug wires has a good solid connection. Could also check to be sure that injector on that cylinder is spraying good an not clogging up. Check for corrosion to the harness to the spider. Last but least compression Check on that cylinder or could do that first.. If everything checks out to be ok may have something going on with the computer. Hope this helps
I'll do that thanks for responding
@@halomasterhalo1702 may also check cap, an button something may be wrong with the ignition system. Or like I said dealing with fuel only not enough fuel going to that cylinder.. Hopefully its a easy fix an not something internal. Which is the other reason I mentioned a compression check of that cylinder. Gives a few things to check on. And you are very welcome.
My oil pressure doesn’t read that high but I have perfect level on my dipstick. Runs perfect no ticking.
Check oil pressure switch
Every Chevy in these years I’ve seen have low and erratic oil pressure readings.
What does the tickingmean my 1999 tick Abit on the right side.the oil pressure gauge is cool.but I do here some ticking on that right side.is that normal this is my first v8 chevy.it runs great.
Mines only runs that high on a cold start, about 35-40 warm idling for me
If your chasing a misfire on a 5.7 vortex after having your head replaced especially if it's a 1996 model for cracking make sure that they are truck heads and not Suburban if they are Suburbans they take a different spark plug made by AC Delco I believe it's an RT 41. I chased a damn obscure Miss in mind for the better part of six months and just out of frustration I threw these plugs in it and Bing Bang Boom the damn Miss fire is gone finally.
Thanks for the info I'll have to remember that if I ever have to work on another suburban. 👍
What engine code did u get p0300?
No lights prior to tune up new plugs, wires, cap an rotor shortly after light came on then off then on an off, an back on again. Basically it has a mind of its own I think it likes screwing with my mind. At first it only came on with a/c on or so I thought. At first it said change the 02 sensor did didn't turn light off. Then po300 code MULTIPLE misfire not random don't know if there's a difference between the two. Changed the cap unhooked battery and light stayed off for about 150 miles. On then off and back on again. All I know is when light is on mpg is way worse than normal and with gas prices almost $5 a gallon in CA these days I am basically working to pay for my gas to get to work. Any info would be greatly appreciated. Its a 1996 k2500 153,000 miles.

Your fingers and tools can get in there; not protected pins at all. Pins are easily bent. Check all before connecting. Seat the connector by keeping it parallel the whole time. Can be tricky but a must!
I changed everything and the whole time it was the timing chain
Worn timing chain an components can cause some issues as well.

Amber & Eric Jones the spider thing
@@MrBillybathgate5 yes you'll have to replace the whole spider. Be careful with the plug on the new one cause they are so easy to bend. If one of the prongs bend on the new. It will also throw a misfire code. If for some reason all is well with the injectors an you still throw a misfire code on 3 check the compression. Which that would be the first thing id check an should have done on this truck. Its easy an simple. If all compression is to spec. Then the injectors would be the thing id replace.
Amber & Eric Jones yeah I’m going to take get some practice in at pick and pull before I tear mines apart.

I had to take my 96 Chevy C 2500 2 wheel drive 5.7 l into the shop because both hands were cracked on a truck that never got hot. Replace both heads they did a great job. Got the truck back and I have a miss or stumble under load going down the highway but the truck idle fine. Cleaned and checked and verified the EGR is working properly checked all the spark plugs and recap them replace the cap and rotor and it is installed properly I don't know what the hell to do it's driving me crazy and I don't have a code in the computer they've even hook the big computer up and we drove around and the computer computer shows no problem through the driving range. It's driving me personally crazy
Have you doubled checked to make sure the plug wires are in the correct location from the plugs to the cap? I know sometimes getting them in the wrong location will cause a misfire or stumble may also check to see if your getting spark to all 8 cylinders. Also the injectors possible they could have accidentally bent one of the prongs on the spider injector. If all is good check compression or check to see if one of the injectors isnt spraying.
Hope this helps
@@amberericjones5694 we think alike. That is exactly what I was thinking about the spiders that instead of putting that sweeping Bend IN for number one number 2 and 7 and 8 cylinder they somehow kinked or got it wrong they reused the spiders that were originally on the truck. They had been replaced about five years before I got the pickup. The truck idles perfect. It's only one I put it under load that it starts cutting out or missing if you will. El spark plug wires are pretty straightforward yes I have check them. I have not checked each cylinder for spark I'll get better go tomorrow. If this was an Evinrude or Johnson motor I would already had this figured out. Another thing that is stumping me is I do not have one code on the computer and the light works I've checked that first to make sure that the light wouldn't burn out and my PCM was full of a bunch of codes. LOL I certainly appreciate you getting back to me so fast most people in this world don't give a damn about anyone else.

Dude thank you!!!
i have a 99 suburban 120k miles. replace cap and rotor, fuel pump and gas tank (it was rotted), spider injectors, spark plugs and wires, new ignition switch and relay, new maf sensor, intake. and when the truck is cold it runs fine as soon as it gets hot it starts to sputter a little bit when stopped. when you punch the gas to the floor it just bogs and doesnt want to get out of its own way. i have put 92 octane with booster in to try and clear up anything no luck. i was thinking a cat could be clogged. i get a code of o2 sensors possibly because cat is clogged? never got around to removing them and starting it up to see if that is the problem since the front 2 are before the cat. i also didnt put a stock fuel pump in and also thinking that could be a possibility. any input from anyone would be great thanks!
also turned up the idle a little bit seeing if i could blow anything out or if it just was real low but no luck on that too
Catalyst System Efficiency Below Threshold (Bank 1) this is the code i get too
only thing i can think of is the distributor drive gear could be worn and slipping or my cats are clogged. thats my to do list but input would be great
@@raybanz6686 sounds like cats. If you got a temperature reading gun. You can let the vehicle warm up to operating temp. Take a reading before the cat and after. If the readings are different possible cats are clogged. If they reading the same may just be 02 sensors acting up. Another way you can drill a small hole in the cats an see if there is any restriction from the front of them to the back. So basically you would need to drill a hole in the exhaust in front of the cat check air flow. Then plug that hole an drill one to the rear exhaust behind the cat an check that air flow if the airflow is restricted. Then you have clogged cats. Couple ways to test it.
@@raybanz6686 also May want to check for slack in the chain too. Just throwing that out there. But if its feeling like your not getting enough back pressure or air flow out the exhaust possible clogged cat. But yea I would do that test and see first as I mentioned. May check fuel pressure, compression, etc.
Hi there i have a 1999 chevy suburban c1500 LT. When i turn on my vehicle the windshield wipers starts to going and it's on the off position. How do i fix it and my head lights won't turn on also.

I'm having mis fires after my spider injector conversion. 1999 Suburban. Engine has no power. Does not down shift. What price you pay for your injectors. Mine came from China at $179. I dont think the spider injector is up all the way in the manafold as the top plug does not seat down all the way. Meaning the two clips on the side dont mate properly. And does that white plug go anywhere? Seems to be just plastic.
Repull the connector you may have some pins that may got bent not allowing it to completely sit down. My price will be different than others ppls being I get a complete discount on parts.
@@amberericjones5694 I just check and they straight. Going to wait for a code checker to com in the mail. I know Auto Zone has one, but they wont clear the codes. Suburban ran alright before this, but recently it failed to start due to no fuel pressure. So I got a fuel pump ready to go in also. Fuel pressure jumps to 60 psi, but falls to 45 psi while running. Could be that too.
@@rogermerritt6470 fuel pressure seems alright does it hold fuel pressure with it not running if it holds fuel pressure for at least a hr not running at 60 psi that's good. With it running with fuel pressure at 45 that's not to bad. That's about right.
@@amberericjones5694 It goes down in half an hour. I decided to do the fuel pump also since the fuel gage never goes down beyond half way. I rely on the trip meter. So I clear trip meter when refueling and watch for when it gets down to about 300 to refuel. Have run iot down completly and saw that when it was bone dry the fuel gage shot down to zero fuel level. Getting 10 mpg in town. Terrible. In process of refueling wife's car with my gas since I had just filled the Suburban just before it started acting up.

Lucky you, simple fix. I did the same injectors on my 98 Tahoe, i was driving one day and bam started to mis, bog, lose power, check engine light came on. Code p0300 and the MAF sensor code. Replaced the maf sensor, still misfire. So i had a shop do a diagnostic test, and he determined it was the fuel injection. I ended up doing it myself because i didn't have the $850 to pay😏. So i got everything installed, new injectors, fuel filter. Plugs cap and rotor look ok. Started it up, seemed like it ran good for like a minute or so till it started to misfire again like i never did anything to it. 😫 it has about 198K miles on it. I was looking online and seems like these distributors go out? Idk anyway, these the story of my life. Lol
Jaime G. Yea, this truck did the same thing after I finished it up started with the b.s misfire again. Only code besides the abs sensor. Either distributor or the computer it's self because one minute it would throw a code and idle like crap next minute code would go off and idle perfectly. Owner didn't want to put no more money into the truck so he picked it up a while back.. I would replace the distributor and see if that don't solve the issue.
Jaime G. If you do the distributor, make sure that you are tdc compression stroke. You can put your finger over the #1 plug hole and have a friend bump the key over. After removing the coil pack to keep It from starting. Or rotate by hand. Mark your where your rotor is facing which should be facing driver side #1 cylinder. Mark the position of the distributor. Pull it and the new distributor should drop in. Make sure you put engine assembly Lube on the splines of the bottom gear.
Timing chain
Flywheel split and jumped time on a 96 suburban 4x4. Replaced both. 5&7 misfire. Only code is p1345. Replaced distributor. No change. Swapped engine. 146k truck engine. Drive it in to pull motor so I know it doesn't miss or have compression problems. Get it all together using suburban intake. Guess what!?! 5&7 show 90 misfires in less than a minute and the same code is back.
I have spark. I have compression.

I have a misfire on cylinder 3 on my 1997 chevrolet silverado c1500 5.7 driving me crazy new pugs wire distributor cap and rotor wish I could solve it
What about the injectors? If no the injectors see what compression all the cylinders are at. If cylinder 3 is the lowest on compression an the rest are pretty high then you have something either going wrong with piston rings or other components internally

Can u help me. Having a misfire on cylinder 2. I have already changed coil plugs wires distributor the cap rotor still having the same misfire number two could it also be the Spider injector on my 96 2500
Take one of the coils swap them see if it changes... if not check to see if your getting spark to the plug. If you are. Check the spider Injectors see if that cylinder is spraying. You could have a weak spray on that cylinder or low compression... also check the pins going to the spyder make sure non are bent.
And I would check for vacuum leaks or intake leaks. I would do a leak down once you confirmed spark is good. Then go to the next few other steps
@@amberericjones5694 appreciate that very much! Don't Have individual coils. 5.7 vortec. Did change the one coil though. Afraid of the no compression bc of what I heard possibly having to pull motor to change rings..is this true. Very costly. Rather it be 🕷 injector though its a little work, i can do it myself.
@@creationzthruair834 hoping it's something simple like a vac leak or intake leak or even a injector... if you do a compression test on all the cylinders an say #2 shows really low compared to the other 7 cylinders.. yes motor has to be pulled torn down an new ring's installed. Which will need to be rebuilt.. sometimes rebuilding one is cheaper than buying new.. if it's not ring issues a simple head gasket issue can cause a cylinder to misfire. It can create just enough air leak. To find our you'll need a compression test done. If it jumps let's say up to 210 psi let it sit for a little bit give it about 1hr come back see if the compression has changed if it has dropped a significant amount say down to 200 psi you have a leak somewhere in that cylinder either rings valve seals etc... you then can also perform a leak down test with a fog machine and what it will do is let you see of you have any Intake leaks it may also pick up head gasket leaks too if any.

I have a 98 Suburban 5.7 with 216k miles. It idles well, but has a misfire on one cylinder only under load, worse when engine is cold. Only one day after running injector cleaner and running it hard, it ran perfect. then next day misfire was back. I have replaced the plugs, wires, cap, and rotor. My guess is clogged spider injector. Do you think it'd be worth it to try having the injectors cleaned? ($100) Or should I just replace the whole assembly?
btw, there are no codes.
@@camarokurt you can try to clean them first. But while your there may just wanna replace them. Also you may want to get a compression tester and just see what the compression is on all 8 cylinders... Because too low of compression will cause misfire an also hesitate under load.. But if youve ran fuel injector cleaner in it an seen a improvement more than likely fuel injectors are probably getting clogged up.
@@camarokurt Also wouldnt hurt to do the fuel filter the same time as the spider injectors. Because any trash that may be left in the system may clog the new injectors. Just a quick thought

What cylinders are you misfiring on.
Amber & Eric Jones If im not mistaken I believe it is cylinder 4
@@Malikamos1 do a compression test on all the cylinders. Be sure that all cylinders are running very close to the same psi. Lets say for instance cylinder 1 is 285psi cylinder 2 is at 280 that is fine that means their running really close to the same numbers cylinder 3 285 cylinder 4 is at 165 cylinder 5 270 cylinder 6 270 cylinder 8 274 cylinder 9 270. If they are reading close together or right around the same but 1 or more is showing way low. It is a good possible could have a stuck valve, bad piston rings on that cylinder or a valve seal/seat leaking. But usually that one will result in smoke an is very noticable on start up then goes away after its warmed up... But other option is either failing piston rings stuck valve etc.
@@Malikamos1 also may want to be sure that you dont have a pin on cylinder 4 injector bent. If So that will also cause a misfire. Double check your pins first then go through with the compression test.
@@Malikamos1 even a failing head gasket can also determine low compression. But usually it'll be more than 1 cylinder on that side..

Did you do a complete spider swap to the new mpfi
barry cowan i put in a brand new spider injector for the 5.7
Actually, the one that he showed in the video, as the old unit, is an updated one, already!! There were some older units still out there, when some of these went bad, and needed to be replaced. But that one he replaced, was the updated version, of the mpfi spider!
I have literally replaced everything all new sensors and injectors new timing chain distributor wires plugs o2 sensors everything you can think of minus the pcm. And I keep getting p0300 and p0102 and open circuit for right abs sensor. I’ve checked the wiring harness and can’t find anything super annoying literally spent so much money. Super weird when drive at highway speeds 65-70 it will start miss firing and after driving and I put it in park it will idle super low and try to shut off. Also when I put my turn signal and try to accelerate it hesitates and starts bucking super weird.
Have you checked fuel pressure and or compression or both
Bucking can be due to fuel pump or filter or fuel injectors not spraying right. Or compression can be a culprit as well
@@amberericjones5694 yes I’ve changed the fuel pump twice just to make sure it wasn’t bad also changed the fuel filter and the fuel regulator. Engine runs super good just acts weird at times and can’t figure it out . You know the weird part is the p0102 won’t clear at times along with the abs code.
@@raymondc.3003 p0102 mass air flow
Amber here! After looking some things up I seen that the p0102 code and one of the fixes is the air filters did you happen to check those?
Informative video but as a skilled mechanic,why would you start the vehicle without putting oil in the power steering first!?! You risk burning up the pump with no oil!
Pwr steering pump was already going out I mentioned it to the customer to replace it but he didn't want put more money into it. But I did put pwr steering fluid in it after wards I didn't run it that long just enough to show everyone that misfire was solved. But no, pwr steering pump was already going out the door anyhow. Trucks used as a deer hunting truck anyhow. And by the way his father got him a new vehicle now this vehicle just sits not being used 🤣
Now if he had me replace it I would of turned the wheels lock to lock before starting the vehicle to bleed air out of the system. And would have made a full on video on how to do that. So hopefully that clears the air
I thought that might of been the case but you have to cover your bases knowing better that any pump or motor operateting without oil is going to be at risk of damage! I was trying to be helpful bro,any loved the video learned something new! Keep um coming! P. S.- this is the first thing I have ever remembered liking, subscribing and commenting on! Stay blessed!👍
@wallcottmoss3028 always man yea I wouldn't do that to a good pwr steering pump if that was the case. Your good man. I need to get back on here more been on tik tok more with all my mechanic vids. Most of the stuff I'm doing someone out there has already covered it.
@wallcottmoss3028 TH-cam has grown alot since the past few yrs
all talk with this video
Maybe all talk but I'm explaining a misfire problem that can be fixed if somebody is changing out a spider injector on these engines. Thanks for watching.
@Ed Al thank you for watching, I'll keep explaining for those that wants to learn something. You keep watching those videos that don't talk at all and don't explain nothing. Have a nice day.
@Ed Al if you paid attention I would have made a video on how to do the spider injector on this truck. But I was in a rush to get it done. So I made a video explaining the issue and how I fixed it. To help those that may run into the same issue. Take me with a grain of salt if you already know how to fix something no need to watch these videos. If not shut the hell up and pay attention you might learn something
Sounds like “saved by grace through faith” could reciprocate that grace given you explained you wish you had done a video on changing out the spider injectors. Thanks for sharing what you found.
If you love working on vehicles then get a chevy. They are constantly having issues. I've owned three in my life and will never own one again.
Only thing good about a chevy is the engine everything else is trash
I think chevys the only truck that the tail gate handle breaks 🤣 electrical issues, tyranny issues, drive shaft falls out, dashes all plastic and breaks under minimal pressure, fuel gauge issues and the list goes on 🤣🤣🤣
@@amberericjones5694 agreed, they all have the same exact damn problems. Design failures in my opinion. But they do have a reputation for having a strong engine.
@@roostercogburn2365 like I try to tell ppl including my own friends. Chevy did wonders for their engines. They put more thought process for hp and reliability. But they skipped out on everything else. Now, if they would have put that same thought process in hp and reliability as they would of the entire truck or car they would of probably beat Ford in the long shot... thing with Ford they built their vehicles to work hard they put the thought process in everything in certain vehicles. Not going to say all because they have some that are trash like the f150 and their 5.4 triton engines.. but as far as it being used as a work truck like when they put the thought in the Ranger they topped it...
They made those rangers indestructible damn near. I still have mine and still looks just as good. The other thing chevy cheaped out on is their paint. If you compare a chevy to a box car. It's like putting in a 454 in a box and driving it. Lol although ford did also build performance as well they also didn't skip leg day 🤣
