Going through this right now. My first thoughts were I need spark plugs. Either cylinder 7 or 6. Gone try it out and come back to the video. Thank you my guy
2012 Silverado, mine did the same. New plugs and wires, cleaned throttle body, mass flow air sensor cleaned and the electrical connector, checked and tightened air cleaner, Lucas in the gas tank. So far so good. Will keep an eye on it
I know the problem! I forgot I commented on here before I figured it out, but I do know what it is now! It has nothing to do with throttle body, or anything else! It's actually an issue with the connection between male and female connectors in the main fuse block! I came across an article that explained it perfectly, and it lead to us using dialectic grease on the connecting pins, and replacing the bolt that holds the block together, and it worked!
Ok so today I did a tune up thought changing the oil might as well do plugs and wires had no misfire issues prior,used exactly the same plugs auto light double platinum went for a drive about 30min in started to misfire and stable track light came on flashing check engine light everything describe in video description went and grabbed new wires no change read a hundred forms with a hundred different check this check that clean this change this after being very frustrated I decided to put the old plugs back in and check the gap on each on as I pulled them out supposedly come pre gapped so I was told nope 4 out of 8 where way off anyway stable track light off on misfire runs grate again in short go ac Delco I will never buy autolite plugs again if this helps please share it God bless
Happened to me about 1 o’clock this morning. Watched your video. Woke up, went to O’Reillys got a spark plug. Number one cylinder was misfiring. Quick easy fix. Thank you.
I have a 2008 Silverado exact same issues as yours I change the plugs and wires and it ended up being a lifter was collapsed I even drove it like that for three years with a collapsed lifter taking it easy
2012 GMC sierra 1500 here. changed plugs, worked for a week then started it again. changed wires (thought i saw some rubbed insulation on #5), no effect, still doing it. changed coil pack (v6, the single pack up in the back where distributors used to go in the old days). thought that had fixed it as it ran great for 5 weeks. then started doing it again this past monday. I know its electrical in nature and not the stuck lifter that others have described, since if you take both battery leads off and let it sit for an hour to fully deenergize/reset. then hook it back up and go for a drive everything is fine. but when you turn if off and start it up again, it starts doing it straight away. I don't think my engine has AFM since its a V6 but i could be wrong. Could it be the ignition control module? something bricked in the ECU? idk. i just want to get this thing fixed so i can sell it and be rid of it. I got a BMW with 100k miles on it that's more reliable than this truck has been with only 47k, since day one. Freaking ridiculous that an american made truck is this shitty. Think i'll buy a nissan...
I think is a vacuum leak years ago I had a suburban and it was misfiring I had a good mechanic who fix it he open the intake manifold and there was the vacuum leak he had to rent a machine in autozone to detect the air or something like that problem solve he charge me 800dls, sadly I had a yukon now with the same issue but not everyone really find out what the problem is I'm pretty sure is the same since I had the suburban and it ended up being a vacuum leak
I have changed my mass air flow sensor and that didn't fix it so I changed my spark plugs and wires and that didn't fix it so I bought a scanner and it read a misfire in cylinder one and I'm thinking it might be a lifter. Any ideas cause my truck runs rough and the stabilizer and traction control light is on with the check engine light blinking I'm about ready to just roll the bitch off a cliff
@@jonathanoverton4950 if your truck is running rough and it says service stabilizer and traction control light is on it is probably what my issue was a stuck lifter
My 2015 Chevrolet Silverado has 57,002 miles. Engine light came on and the dealership mechanic said I needed a engine rebuild due to a stuck lifter and misfire on cylinder #1. $5k in repairs on a vehicle less than 5 years old. GM mechanic said it was a common problem. GM is trash in reliability.
I just had the same problem on my 2013 Buick regal turbo and it told me I had a misfire on cylinder 3 and the same lights came out on the dash in video and it was off because I had changed my sparks a month ago with high end ones and so my mechanic changed them and I took the car and it shut down on driving home but this time same dash lights but it said it needed a coil on bank 1 had it changed and the car runs perfect so far. Don't trust the dealership, take it to autozone if you don't have a code reader and see what the cars computer is saying.
I've had it happen to me twice. I ended up finding on of the lifters was collapsed. Put solid lifters in it and a delete kit. Ran fine for a while. Now I have the stupid stabilitrak light and loss of power. Othing like the loss of power when the lifter collapsed so I know it's nothing to serious. I replaced all grounds and both battery terminals. Cleaned up all connections and still doing it.
Hello, I recommend the Phoenix Elite from Topdon to you. I am also using it, and I think it is very good. The functions and coverage of the models are very complete. Here is a video of me using this device to reset the engine Oil Light for the 2016 GM Suburban: th-cam.com/video/M_4W8pUm6_0/w-d-xo.html , you can refer to it, maybe it will help you!
The gunk is from the oil build up from afm shutting down lifters to kick in 4cylinder use. Design flaw many channels have videos on that subject. I just found out as I would be upset about my plugs being fouled out. Change oil and clean injectors time to time
my 2010 chevy avalanche did the same thing i ignore for months then all of a sudden one piston snap on me going up a hill and mest up my cam too had to overhaul my engine
A few years ago I had the same issue, replaced the plugs and problem was solved! thanks for sharing, I hope more people check on their spark plugs before they spend a ton of money.
I’m in need of help!!! I have the same issue, cylinder 1 misfire. I changed all wires and spark plugs and still have the same issue. Anyone else know of any other ways I can fix? I have a 2007 Avalanche 5.3L
Did that that didnt solve the issue so i replaced my coil packs on my gmc acedia 2015 it was a cylinder misfire 1 only other issue can be fuel injectors.
Had this happen yesterday blinking check engine light and service traction control and esc off car was also rough idling engine shaking bad. Changed all 6 spark plugs and my lights went off for now will update in a few weeks or a month
My 2008 did this exact thing this morning when i left for work. About a mile from home. Lost engine power during this little episode also. Jumped in my car and went on to work and made a day and when i got home i cranked the truck and all the lights are now off. Does this sound like the same issue you was having?
This is also my Tahoe at the moment, I’m selling it for 5,300 because I don’t have the time to fix it since I work, but it’s assuring to know it’s a simple fix in case I need to raise the price once I fix it
You have an oil consumption problem which is why your plugs have so much buildup on them. Normally, these plugs will easily go 100k miles without failure and then only the gap begins to widen causing an occasional misfire.
i have the same exact issue i replaced the spark plugs replaced mass airflow sensor and cleaned throttle body works much better but still getting miss fire im guessing imma have to check for a bad coil
Same thing here so I replaced the coil and still have the misfire so turns out it might be the fuel injector, gonna go ahead and replace all of them tomorrow and we’ll see.
@@Goodoltimer no i pulled the fuel rail and all that what ended up fixing the issue was changing out the o rings on the injectors and the seal on the intake manifold the rubber was just old on all of that, also lesson learned get ac delco for your chevy/gmc dont cheap out on autozone parts XD
Thank God found your video, the exact same thing happen to me, about the same distance but they lights turned off once I got home, but I checked on the computer and it also says a misfire on cylinder 7 same as you and it was pending, so good thing I saw your video cuz I was starting to stress out. Let's see if that fixes my problem.
I have a gmc sierra 2007 same lights on but it rides good until the light comes on and shift hard when it shifts 1st gear. Do you think it can be the spark plugs? Any idea
Same make and year, same issues as yours. Runs fine until stabilitrak turns off, shifts hard from 1st to 2nd, then runs fine after that. Only does this after stopping and idling. Anyone get a diagnosis for this yet?
Thank you so much for making this video. I had both stability track and traction control light go on December 2020. Paid for the full AAA membership to have it towed the next day to have it investigated at the Fix-It shop. My roommate told me he would have a guy come out and hook it up to a device that would tell us what was wrong with it. He told me I needed a brand new transmission and quoted me $7,500. Mine is a 2007 Chevy Suburban with 120,000 MI on it. Then my roommate took out the battery because he told me my battery was bad even though it was just 6 months old. He said he hooked up the little device and it just said; "Error"reading. Every night I've been dreaming it was a spark plug wires or the spark plugs themselves. I have been told that I am an empath and have wondered if I have some kind of connection to my car since the whole time I thought this was the issue but my roommate told me I needed another transmission. My car has been driven like it was a Bentley. Maintained in pristine condition with full Chevy dealership maintenance every 6 months in St George Utah but they were still never able to figure out how to stop the light that said; "Tire pressure monitoring system" even though I got brand new tires. Just come to the realization that I am indeed smarter than a man! Never believe anything a man tells you unless he is a qualified vehicle maintenance person.
Spark Plugs? People don't change them things till they are 50k miles past due. Plugs are cheap, but for some reason half the population does no change them till the car barely runs. What they don't realize is for the prior year they got 3 miles less per gallon burned. 30.00 set of plugs cost you 200.00 in extra fuel last year.
I also had same problem went to oreillys had them hook up Obd and said was cylinder number 7 so I bought 1 one spark plug boom was fixed the next day replaced other 7 and cables running like a champ now
There is a wire with a small plug on it that me and a guy from O'Reilly's found last year, after my truck started doing this. Plugged it back in and engine was smooth, all lights went off and I was able to remote-start my truck again. I don't remember which side of the truck we were on so I'm looking for it again - if you know what I'm talking about, please share.
@@waynemcshan6306 are you talking about a ground strap are ground wire.ive seen people have all these lights on and tighten are replace ground wire and fixed problem also could be wheel sensor ..
I have a 07 6.0 Silverado vortec max. Was towing a light load one day. And something gave in the engine bay. All the same lights came on in the dash. I took it to a few mechanic shops, cylinder 7 misfire. They took the top end off and said I had a bad rocker arm. I’m now looking at a 5k motor to drop in it.
This is exactly what's happening to my 2007 chevy tahoe but I changed all the spark plugs plus the wires for the spark plugs still having the same problem 😫
I'm going through the same thing but my Inj-B fuse #13 on fuse box keeps burning I changed it drove half a mile as soon as I passed a bump it burned the fuse I try the scanner it said coil #2 #4 #6 #8 I changed those today and it keeps doing the same thing
Mine did the same thing. Work for about 600 miles. Now it’s doing it again and it didn’t work the second time… little white smoke on start up sounds like it’s runnin on 4 cylinders and ticking… any suggestions folks?
2010 - (100K on it) cylinder #7 -> due to drivers side valve cover pcv valve "rail" defect from factory (smothered plug basically with oil)... I replaced the valve cover with new designed one, replaced all the plugs/wires, new air filter (clean MAF sensor as well), changed oil, cleared codes (battery unhook - (-) neg side for an hour... hooked back up,,, varroooom!! good to go!!...thanks... _DTM
Yep, 2011 GMC Sierra 5.3 here. Like clockwork, once a year, cylinder 7 goes on me and I only change that one usually to get me by. I changed the plug wire a couple years ago also. Also common is the low oil pressure issue, which typically the sensor goes on these or gets plugged up, so changed that out today and running like a top...for hopefully another year :)
Same exact problem as my 2011 silverado 5.3 😆 just changed the coil and plug today,oil pressure acting up,changed the plugs and wires 2 years ago,was a bad spark plug in cylinder 7,just ordered the Range disabler.145000 miles
Yes it did thank you very much mine went off yesterday I pulled into an advance they put the code thing on it it said it was admissions so I added some fuel cleaner to it but it did not clear so I'm thinking it is the spark plugs once again thank you or do you have to clear it manually
@@elishaduncan2479 on the real im bouta do that right now...i already changed the pedal senor the brake light senor i cleaned up the battery got new battery terminals took out the throttle body cleaned that out if that tuneup wont work might just need a throttle body
Lol........ I had the same problem a year ago on my 08 Avalanche ltz........ACDelco D1539J GM Original Equipment Brake Light Switch Fixed the problem. Look it up if this method didn't work for anyone in comments. Great video 👍
@@stephaniehernandez1317that is a lifter failure because of DOD/AFM sometimes the lifer can be unstuck but usually need a DOD delete and tune the computer to remove the AFM/DOD codes
@@brianreynolds4149 mines is still doing it after replaced all spark plugs wire, throttle, couple of sensors air mass gas evap and idea what it could be ?
Sooo I had this exact problem and I did the complete tune up and changed the oil dip stuck but now 1 month later it’s still doing this.. what else could I do? I need help😭
This is exactly what is going on with my truck same exact year ..I have found to check your ground wires first also check you voltage on battery terminals seen this with many of these trucks with all lights on and I've seen where it was the whelp sensor but ton when stop raining I'm gonna start with loose ground strap and wire my truck don't have the one from body to hood and then gonna check the one from body to block ..
If you find out what's going on with yours let me know what it was .. I just watched several videos and talked to my mechanic he thinks it's a wire issue and seems alot videos I watch that's the case but if not prob wheel sensor he told me to unplug and clean are wiggle then and see if go off . But I hope just ground problem mine happens more when rains and also my trans will shift hard into 2 and not as strong power and my light on dash and radio dim and sometimes they come back bright ..but I seen where someone fixed there ground wire and everything went away they even had the trans problem witch is so strange it only happens sometimes and usaily if I let truck warm up for awhile don't do it..
I have a 2008 Sierra ~ 188k and was experiencing the same - service traction control, service stabilitrak, and reduced power. Took off my valve cover and started the engine for a sec - could clearly see one rocker arm on cylinder 4 wasn’t moving at all. Cylinder 4 has those active fuel management lifters on it that are prone to failing over time. Took my heads off and sure enough… had a bad lifter on the rocker arm that was not moving. Hope you get yours figured out 👍
@@gueroburban4989 yeah I'm going to replace all the spark plugs. I was having a issue with the negative cable causing the doors to lock and unlock and go in neutral. I fixed that now im having a issue with the traction control.it happened before and I replaced coil springs and number 7 spark plug now I think 6 went out or the battery could be the cause since its been a while since it been replaced
I hit a bump hard, the stabilitrak and check engine appeared on my dashboard. The crazy thing is that looks like the engine Is knocking. At autoZone I was told it’s cylinder 1. Could it possible be the plugs too?
Is it a tick or a knock... There is a BIG difference. If its a tick you need to have your oil pump and lifters done which can be pretty pricey unless you can find a good honest mechanic
Mine just started doin the same thing today! 18 z71 19k on it. I was in 4WD driving through freezing rain and snow. I was stopped at a light turned green the tires were spinning a little then my check engine light started blinking and my traction control light popped on as well but it turned off a few miles later. I’m going to take it chevy in a few days but I’m kinda nervous to drive it.
@@josebernal6631 not yet I get it towed tomorrow. We’ve had so much snow and ice our city has been shut down for days. On star did sent me a message saying I had an issue with my emissions but why would that cause my CEL to blink?
08 suburban ltz 197000miles 4x4.. same here with me. Number 7 was BURNT. Within the last 4 weeks I've done this: All spark plugs & wires, MAF sensor, cleaned throttle body(without removing it or forcing it wide open), seafoam in 2 fill ups, installed range AFM disabler, fuel system cleaned and flushed at shop, driver's valve cover. After all this I'm still getting CEL, traction control and stabilitrack. I had rough idle AND hard shift BEFORE touching throttle body. I'm not giving up so next I'll test my coils.. I also wanna add that I unplugged my old MAF sensor and the truck kept running, however, when I slowly plugged it back in the engine attempted to die. When I installed new MAF sensor I repeated same steps and the engine KEPT RUNNING. I ended up keeping my old maf in storage and left the new one on. I absolutely despise seeing ANY dash lights!! Any suggestions besides scrapping my truck?
@@NOSJNKY-yu4jz it worked for me but try it out this is most likely the case a bad ground or bad positive battery cable. Check your engine ground by the fire wall too.
GM corporation owes all of us a refund for buying their vehicles
My Silverado just did that, went to Dr TH-cam found your video I appreciate you making the video, saved me a lot of time effort. Thank you Sir !
This made my day… “Dr. TH-cam” I’ve never thought of it that way before. Thanks. Not only a doctor but a mentor as well…

You are smoking that DANK kush if you think you're "connected" to your car...
Spark Plugs? People don't change them things till they are 50k miles past due. Plugs are cheap, but for some reason half the population does no change them till the car barely runs. What they don't realize is for the prior year they got 3 miles less per gallon burned. 30.00 set of plugs cost you 200.00 in extra fuel last year.
30 for plugs I have 16 plugs at 11 to 15 each ! Good for hundred thousand miles
I also had same problem went to oreillys had them hook up Obd and said was cylinder number 7 so I bought 1 one spark plug boom was fixed the next day replaced other 7 and cables running like a champ now
It’s not the spark plugs that would cause this
Yes bad spark plugs can cause a misfire.
There is a wire with a small plug on it that me and a guy from O'Reilly's found last year, after my truck started doing this. Plugged it back in and engine was smooth, all lights went off and I was able to remote-start my truck again. I don't remember which side of the truck we were on so I'm looking for it again - if you know what I'm talking about, please share.
yea thanks that was alot of help...jackass
Where is the small wire?
@@gueroburban4989 I still don't know. I was hoping a mechanic would answer the question.
@@jameslyons2421 I asked a simple question jackass. I was hoping a mechanic would answer the question, jackass.
@@waynemcshan6306 are you talking about a ground strap are ground wire.ive seen people have all these lights on and tighten are replace ground wire and fixed problem also could be wheel sensor ..
I have a 07 6.0 Silverado vortec max. Was towing a light load one day. And something gave in the engine bay. All the same lights came on in the dash. I took it to a few mechanic shops, cylinder 7 misfire. They took the top end off and said I had a bad rocker arm. I’m now looking at a 5k motor to drop in it.
You can replace the rocker arm without getting a new motor I did
@@bundywhitmore9671 I’m so glad I’m going this route. I decided to not buy a new motor and do a rebuild. Thank you
This is exactly what's happening to my 2007 chevy tahoe but I changed all the spark plugs plus the wires for the spark plugs still having the same problem 😫
I'm going through the same thing but my Inj-B fuse #13 on fuse box keeps burning I changed it drove half a mile as soon as I passed a bump it burned the fuse I try the scanner it said coil #2 #4 #6 #8 I changed those today and it keeps doing the same thing
Mine did the same thing. Work for about 600 miles. Now it’s doing it again and it didn’t work the second time… little white smoke on start up sounds like it’s runnin on 4 cylinders and ticking… any suggestions folks?
Thx you
Changed spark plugs and wires and still same issue , any one else have an idea of what it could be
2010 - (100K on it) cylinder #7 -> due to drivers side valve cover pcv valve "rail" defect from factory (smothered plug basically with oil)... I replaced the valve cover with new designed one, replaced all the plugs/wires, new air filter (clean MAF sensor as well), changed oil, cleared codes (battery unhook - (-) neg side for an hour... hooked back up,,, varroooom!! good to go!!...thanks... _DTM
Mine just did this again but this time the with the flashing engine light and knocking noise
I just had the plugs changed last summer and there is plenty of oil. So I’m not sure why it’s knocking
GET TO THE POINTTTTTTT. GEEEZ TO MANY PAUSES, UM's AND UH's.
Yep, 2011 GMC Sierra 5.3 here. Like clockwork, once a year, cylinder 7 goes on me and I only change that one usually to get me by. I changed the plug wire a couple years ago also. Also common is the low oil pressure issue, which typically the sensor goes on these or gets plugged up, so changed that out today and running like a top...for hopefully another year :)
There’s an oil consumption issue with these trucks. Change the driver side Valve cover & you’ll be good
Same exact problem as my 2011 silverado 5.3 😆 just changed the coil and plug today,oil pressure acting up,changed the plugs and wires 2 years ago,was a bad spark plug in cylinder 7,just ordered the Range disabler.145000 miles
@@scottrobinson2286 how’s your truck doing now?
Thanks man, I appreciate the video
Yes it did thank you very much mine went off yesterday I pulled into an advance they put the code thing on it it said it was admissions so I added some fuel cleaner to it but it did not clear so I'm thinking it is the spark plugs once again thank you or do you have to clear it manually
Im having same problem now
Mine just started doing this after changing the radiator. I replaced the spark plugs 1 month ago. I'm gonna run the codes to see what it's saying
Hmmm... just got this problem..
When this happens it could be numerous things
My 2009 Tahoe light keep coming on and flashing already changed spark plug on clinker 6 and ignition coil what do I do now to fix it please help
2008 sierra and is doing the exact same. Just changed plugs and wires.
Great video, hope it helps. Thanks
Yes and both have also been replaced along with throttle position sensor... maybe a miss fire? Maybe a coil pack, o2 sensor or stuck lifter
I have a GMC Yukon 07and it did the same thing great video same fix.
I have the same vehicle with same what did u do exactly tune up u think
I changed all the plugs and wires and clean the throttle body and it runs like a champ
@@elishaduncan2479 on the real im bouta do that right now...i already changed the pedal senor the brake light senor i cleaned up the battery got new battery terminals took out the throttle body cleaned that out if that tuneup wont work might just need a throttle body
Bro I got ah 2008 gmc xl 1500 just happened too me right when I was about to get home hopefully this is the solution this vid great info bro
Kind of results you can do without.
Thanks
Awesome tips Brother but I did replace the spark plugs and wires I’m still no solving the problem….
Changed my plugs and still doin the same thing
Have a 2010 replaced alternator solved all problems so far 2000 miles no problems
what problems did it solve?
Door locks, locking, unlocking, traction control going off all the time replace the battery cable negative and alternator
Any updates
Mine started today
Yes
Lol........ I had the same problem a year ago on my 08 Avalanche ltz........ACDelco D1539J GM Original Equipment Brake Light Switch
Fixed the problem. Look it up if this method didn't work for anyone in comments. Great video 👍
No.... You should check your spark plugs...
Our 2013 Yukon did this right after a tune up and all spark plugs were new. We tried replacing the ignition coil and so far so good. 🙏🤞
Did your start making a loud noise when it happened like the lifters where bad?

@@stephaniehernandez1317that is a lifter failure because of DOD/AFM sometimes the lifer can be unstuck but usually need a DOD delete and tune the computer to remove the AFM/DOD codes
No misfire fixed
Very good bro
The plugs and a coil DIDN’T work for mine. My lights are still lit.
My 07 tahoe is doing it . Took it to shop said it was a bad lifter
You clear the code?
#1 cylinder is dead . Did a compression test. Reads 0
@@brianreynolds4149 mines is still doing it after replaced all spark plugs wire, throttle, couple of sensors air mass gas evap and idea what it could be ?
@@aidezamarripa3746 I would get a compression test on engine . Once I saw that #1 cylinder had 0 compression I went to the rebuild phase.
C'hanged all of mine and the wires...still does it. Any thoughts?
Does your 4WD HI engage when the Stabilitrak light comes on?
Check ur exhaust system that was my problem and it stop once I replaced it
@@torrancebanks6888 did it throw off a cylinder misfire too?
It threw off multiple cylinders to the point my truck was shaking when I drive
My Cadillac Escalade does it to change coil. Packs and plugs
Sooo I had this exact problem and I did the complete tune up and changed the oil dip stuck but now 1 month later it’s still doing this.. what else could I do? I need help😭
Have You Found Anything else ??
Same thing
Change the valve covers and seals!
Change your negative battery cable there’s a recall on it you need the new cable you will thank me!!
Clean the throttle body it will help to
A bad wheel hub/wheel bearing will also cause traction control and abs problems. Had this happen a few times.
Changed mine out and the codes didn’t go away, even after clearing them. No engine light, just brake, traction control, and stabilitrak
What about when experiencing Engine power is reduced, Service traction control and service stabilitrak in a 2011 chevy Silverado 1500 truck?
This is exactly what is going on with my truck same exact year ..I have found to check your ground wires first also check you voltage on battery terminals seen this with many of these trucks with all lights on and I've seen where it was the whelp sensor but ton when stop raining I'm gonna start with loose ground strap and wire my truck don't have the one from body to hood and then gonna check the one from body to block ..
If you find out what's going on with yours let me know what it was .. I just watched several videos and talked to my mechanic he thinks it's a wire issue and seems alot videos I watch that's the case but if not prob wheel sensor he told me to unplug and clean are wiggle then and see if go off . But I hope just ground problem mine happens more when rains and also my trans will shift hard into 2 and not as strong power and my light on dash and radio dim and sometimes they come back bright ..but I seen where someone fixed there ground wire and everything went away they even had the trans problem witch is so strange it only happens sometimes and usaily if I let truck warm up for awhile don't do it..
I have a 2008 Sierra ~ 188k and was experiencing the same - service traction control, service stabilitrak, and reduced power.
Took off my valve cover and started the engine for a sec - could clearly see one rocker arm on cylinder 4 wasn’t moving at all. Cylinder 4 has those active fuel management lifters on it that are prone to failing over time. Took my heads off and sure enough… had a bad lifter on the rocker arm that was not moving.
Hope you get yours figured out 👍
I just got this this week my dumb ass filled it with flex fuel 83%...blinking cel and traction lights should I run it out then go back to octane?
My engine light only blinks when the stabilitytrak comes on too so should I replace the spark plugs ??
Change your negative battery cable!! There’s a recall on it you need updated cable you will thank me

Look it up fixed mine no problem.
@@gueroburban4989 just did that and now the issue happened
@@clapzy2943 try your positive cable and mega fuse
@@gueroburban4989 yeah I'm going to replace all the spark plugs. I was having a issue with the negative cable causing the doors to lock and unlock and go in neutral. I fixed that now im having a issue with the traction control.it happened before and I replaced coil springs and number 7 spark plug now I think 6 went out or the battery could be the cause since its been a while since it been replaced
I hit a bump hard, the stabilitrak and check engine appeared on my dashboard. The crazy thing is that looks like the engine Is knocking. At autoZone I was told it’s cylinder 1. Could it possible be the plugs too?
Any update did you fix the issue
I did the exact same thing, is there any update because I’m nervous to drive it home
Is it a tick or a knock... There is a BIG difference. If its a tick you need to have your oil pump and lifters done which can be pretty pricey unless you can find a good honest mechanic
Mine just started doin the same thing today! 18 z71 19k on it. I was in 4WD driving through freezing rain and snow. I was stopped at a light turned green the tires were spinning a little then my check engine light started blinking and my traction control light popped on as well but it turned off a few miles later. I’m going to take it chevy in a few days but I’m kinda nervous to drive it.
Do you find the problem?
@@josebernal6631 not yet I get it towed tomorrow. We’ve had so much snow and ice our city has been shut down for days. On star did sent me a message saying I had an issue with my emissions but why would that cause my CEL to blink?
Oh and my oil pressure gauge was move up and down a lot
@@Fox250R , let me know when you fixed , my do the same thing ,thank you
@@josebernal6631 Been @ Chevy for 3 days. They cant find shit!
08 suburban ltz 197000miles 4x4.. same here with me. Number 7 was BURNT.
Within the last 4 weeks I've done this:
All spark plugs & wires, MAF sensor, cleaned throttle body(without removing it or forcing it wide open), seafoam in 2 fill ups, installed range AFM disabler, fuel system cleaned and flushed at shop, driver's valve cover.
After all this I'm still getting CEL, traction control and stabilitrack. I had rough idle AND hard shift BEFORE touching throttle body. I'm not giving up so next I'll test my coils..
I also wanna add that I unplugged my old MAF sensor and the truck kept running, however, when I slowly plugged it back in the engine attempted to die. When I installed new MAF sensor I repeated same steps and the engine KEPT RUNNING. I ended up keeping my old maf in storage and left the new one on.
I absolutely despise seeing ANY dash lights!! Any suggestions besides scrapping my truck?
It’s your negative battery cable there’s a recall on it you have to put the new updated one try this I’m 95 percent that’s it! You will thank me!
Did the neg battery cable work?
Did negative battery cable fix problem?
@@NOSJNKY-yu4jz it worked for me but try it out this is most likely the case a bad ground or bad positive battery cable. Check your engine ground by the fire wall too.
