Glad I found this video, I've been on the fence about the injector upgrade but I've done the IAT relocation, bored TB, and glasspack, TV cable adjustment. Now the injectors and new Coolant temp sensor are the next on the list. What you said at the end is also bizarre, because I've seen a few ZJs like mine (95) and XJs with the 4.0s and they all seem to have a discernable lack of power compared to mine. Maybe our Jeeps were just built on Monday....take care man I'll check out your other videos. Hope you still have your jeep.
Dude!! I am glad I stumbled across this video! I have been fighting my heat soak issue for a while now, and was looking for a way to upgrade my ECU. I was told that upgrading the ECU was what I needed to do...Looks like if I move my intake sensor that may do the trick. I have a 2000 XJ and when Summer hits so does the flashing check engine light. Hopefully your little trick will work for me. Thanks again and have a goodern! Gonna check out your other vids! :D
I have a similair thing going on now. It seems to be old plugs and maybe clogged injectors. If you're running tip top you shouldn't have a misfire or check engine at all...
My jeep looks just like yours..only thing different is....I got rid of my coal springs. Zero springs...all fox shock all the way around. Super extremely smooth ride. I'm on 38s 8.25 rear 30 In front 4.56 ratio. I'm sitting 9.5 inches high plus I did the 1 ton conversion..I don't have a jeep channel but you can spot my jeep on my channel I'm commenting from. Check it out...
guys the comments I have made on the wife's Trans cooler has caused room for advise the radiator is only a heater for the Trans to the point the Trans gets hotter than the engine this will happen quickly when pushing the Trans there is two reasons for most Trans failure broke hard parts and overheating so don't run just a external cooler unless you are positive it is adequate
Rusty 411 when you live in a climate where temps get to zero and below. it takes quite a long time for the trans to heat up (it doesn't like running cold) the engine in comparison heats up very quickly. so the trans lines run through the rad. to get the trans fluid up to temps
Karo Staro yes Def you need the rad to heat up the fluid in That situation I have never seen snow lol we have nothing but hot here in FL lol thanks for the comment as I stated it's only a heater til the Trans get hotter than the engine we see that a lot in Florida Thanks again for the comment have a good one
I moved my tranny cooler to under the back of street car to get away from the radiator and engine heat and dropped 20* temp. I am going to put a fan on it next and see if I can lower it more. I am going to try your mods to my 1999 and 2001 xj. Thanks for the video.
Hey bud the 4 hole injectors do make a noticeable different now put a 1 inch throttle body spacer and another efan where the mechanical fan is and it will have amazing throttle response and better mpgs keep up the good videos hope everything with the Dr's ended up okay
Hey bro I was wondering if maybe you can also write down the mods you do in the description so we can also pull up the video and look at the description instead of trying to search for what you described, like for example in this video it'd be cool to know what year neon you got your injectors from
10-4 man I got ya, I'll try that from now on but on the injectors the ones that fit mine may not fit yours do research on it the ones I got for mine where to short and I had to mod my fuel rail best way is pull one off a jeep same as yours at the yard and match the plug and the height of the injector it is worth the trouble
Manufacturers use the California emissions equipment in everything, just because who knows where the car may end up being sold. The difference is pretty amazing, I could see straight thru the 49 state one I put on.
@@njinthemj52 nice!! I may do this when I upgrade the exhaust and change out the header. Putting a long arm kit that maybe get in the way of the exhaust.
question thats not a mass air sensor. and the temp at the intake manifold is what really matters if the air is to hot then bad fuel usage so why move it? i have a 96 and my intake temp at low movement is up around water temp.so i put hood vents and a fan that blowes down on the intake. temp is around 120ish and i get better fuel mileage. so why move it?
Great videos ...did you run your trans cooler before or after radiator and is there bigger trans coolers that will fit or is that basicly the size u get that fits best with after market like b&m ?
I ran the cooler after the radiator as the factory one was plumbed if you watch my new video all that mudding that day no issues with Temps and before I added the cooler it would have pegged the gauge the first time I got the convertor under a hard load I should really test these mods for a year before I comment lol
+Rusty 411 and my bud has the b&m one on his it fits mine just had a factory one like the one I installed only way smaller it bolted up same hoses all so
Definitely make sure the trans cooler is hooked up the way rusty's is if you drive in the cold at all. When mine ran without the radiator cooler included, it wouldn't shift right in the winter, temps stayed too cool. Connecting it agian fixed it,more fluid capacity is better and its best for the engine and trans to heat up together.
Hey man. what did you use to do the new homemade fuel rail holder. my Injectors I got from a neon are also a little short so I'll have to cut mine also.
I have 98 xj and I've been looking for the next mod to do I've rhino lined the exterior lifted It 6.78 inches tires coming at tax time but I want to do something performance wise and just don't know where to start so blow up my inbox and tell me what y'all think I should do
How are you doing, I have a 92 Jeep xj. Is there a link anyone could reply with to what you would think is the best option for a fuel injector upgrade on my Jeep.. thank you in advance.
Alexander Rodriguez when I installed the new engine I port matched the intake also you can change the intake to the new style and that helps and there's a kit to install a 4.6 dodge throttle body on them I thing 60mm I got plans to further this video when the time comes man
hey rusty I have a 94 and I swapped the 231 transfer with a used 241. I can't find 2 hi. iv taken the linkage of and it clicks in all four positions. any idea.
+Geoffrey nyoni just remove it from the intake and plug hole then drill the intake tube to size and thread in the iat sensor extend the harness to reach the new location and done bud
Awesome Man...I'm up here in NY but Dang we had two weeks of almost 100 degree weather. I put a new clutch on the fan a year ago but it sucks. It's loose already so I am going with this upgrade. Did you have to cut the fan shroud?
+Richard Graham I did a little just shave the bottom to clear past the clutch you may not have to you know there all a little different in clearance or you may be able to lay the shroud back and install the clutch with the shroud lay back on the engine my studs are missing so I had to do it difficult way lol its a good mod
Thanks Man, my 99 XJ needs this Mod because I just installed the Heavy Duty Mopar Rad,190 mopar thermostat, high flow water pump and all new Hoses. yesterday I did a turbo flo muffler and rear pipe. Well the rear pipe had all that stupid plasic and stickers on it that you can't peel off so I decided to let it idle and burn off the labels. After about fifteen min. I came out to have a look and the temp was at about 230 and the electric fan was clicking on and off. That being said, I know it's not pulling enough air so this mod should do the trick. BTW, let me know if you want the info on the HD Radiator. it was only $130.00 mopar oem upgrade.
Hey Rusty love your vids and Jeep. i am having a hard restart when it is hot. and i saw this vid some time ago where you moved the intake air temp sensor. mine be reading 107 degrees when engine is at 195 to 212 degrees. i think i ll move mine off the intake manifold, if you have any ideas on why it is hard restart issue thanks in advance.engine runs ok otherwise except idle is low but within the range for idle. 650 to 700 rpm. also my engine is a Renix and totally stock... thanks
I've heard heat soak can cause rough start. The motor bay of a 4.0L XJ is Hell's kitchen. Sensors, fuel rail, injectors, intake manifold, and other stuff heat soak when the motor and fans turn off. Then you come outta the store with your drink and restart the motor and hear rough idle or sometimes knock. Vent the hood and put a delay timer on the electric fan so it will run for a few minutes after turning the motor off. Yuge help
under the hood of a 2003 4.7 grand cherokee' there are 2 silver line/ hoses a low and top one. whats the name of the lower silver hose it goes from the engine to the fire wall?
now why does the single hole injector make more hp in a mustang compared to a 4 hole and supposedly in a jeep the 4 hole one makes more power. Not saying you are wrong just a question i thought of.
it's just the spray pattern bud probably the reason it seams to make more on the jeeps Is they all have got some age on them and the neon injectors are probably just metering the right amount of fuel I suspect head to head if you used both brand new injectors there wouldn't be much of a difference as far as hp goes in either but they did wake mine up and make it start up quicker all from the junk yard parts is pretty dam good in my book thanks for the comment bud
and also I'm 42 back when I was drag racing mustangs we threw the junk ass fuel injection away back then there was no good way to scan it or monitor anything we had one big 4 hole injector sitting on top called a double pumper holley lmao have a good one man
+Jim m 10-4 I was also thinking the intake runner length on the Ford engine had way more velocity by the time the air flow got to the injectors verses the short little runners on the 4.0 may have a lot to do with the difference in performance on the 4.0 with the 4 hole style you k ow smaller patern for the air flow to atomize maybe
I really like your jeeps. I also have a lightly Modded 99 xj 4.0. I bought it wrecked and I almost have together. I'll have it on my channel. larretta88..
It depends on the year but I have a 99 xj 4.0 and the upgrade for mine is the 4 hole injector #0280155703 which works on 99-04 xj's 4.0 . Just go on e-bay and type in your year and model + fuel injector upgrade and they will pop up. Good luck.
I got a 90 xj.... When i hit the brakes it dies unless i give it a little gas at the same time also it wont start and idle unless i keep on the gas just a bit. I was going to turn the idle up but seen it was screwed all the way in. Im a chevy guy and this is my first jeep. Im pretty lost here.
I wanna see deep water I lived in n ft Meyers and would go to cook and brown and there would be air boats out there let's see the snorkel work and your feet wet do 2000 01 intake swap dremel out your throttle body to the gasket
need to first check the fuel pressure also see if the pressure drops after the engine is off sounds like it bleeding off fuel pressure when sitting that the usual with this problem mine did the same it was the injectors on mine the fuel pump has a Che k valve built in that also causes this problem
it's probably the starter for months I would have to turn and hold the key for 4ish seconds with the engine trying to turn over but it wouldn't then when I turned the key a second time and it fired right up every time on the second try till one day at a Walmart my Jeep wouldn't do anything at all, hit the starter with a pole and hammer and bam started
if you let your jeep sit for a while a hour or more on a hot day, the fuel still in the injectors after you turn it off will be vaporized. so when you try to start it the first time it is not getting the proper fuel. when you let off then try again it get the amount of fuel required to fire up. it is a typical problem hope that helped a little proud owner of 3 xj
HEY RUSTY 🤘Great little mods! .But what did you do to the fan clutch? My 96... I have the mechanical fan and the electric. (A.C. Leave it on) never overheat . My old jeep...think it was a 89..cant remember.....I took the mechanical fan off an added another electric fan and it always overheated...... Just a bigger fan? With more blade?
Had my 92 for 14yrs and has done everything for me, daily driver, hunting truck, camping rig and wheeler all started from a 400$ deal from a friend
I done the Neon injector swap, banks cat back, and a flowmaster cat. made so much of a difference.
did for me to man good deal
how much did all that run you?

thanks bud yeah I think I'll be back at it soon I'll have to try the spacer I want to also get the newer style intake and try that on it
Seth Oliver throttle body spacers only work on carburetors don't waste your money if you have fuel injection
spacers only make a difference if fuel has to travel through to, so only older throttle body's and carbs benefit from it
How do you think this would work on the 5.2? How did it affect your mileage?
Hey bro I was wondering if maybe you can also write down the mods you do in the description so we can also pull up the video and look at the description instead of trying to search for what you described, like for example in this video it'd be cool to know what year neon you got your injectors from

Biggest difference I ever got was replacing stock cat with a 49 state type.
explain more plz
Is the stock cat not 49 state rated?

@@njinthemj52 nice!! I may do this when I upgrade the exhaust and change out the header. Putting a long arm kit that maybe get in the way of the exhaust.
How did you extend the temp sensor wire? I'm thinking about doing this to my 98 ZJ which I'm sticking a High Output motor in.

Just bought an 01 that has nothing done to it.....I did upgrade the exhaust and was going to do the intake....open to suggestions.
Of course there are MAJOR differences between aftermarket transmission coolers.
you should've ran the trans cooler and the radiator cooler in series together, you get more fluid volume and cooler temp
Khris Shultz how do you do this? I’m modding an XJ and admittedly not the best mechanic lol
@@smoore8
there are many vids about adding transmission cooler into xj. I did like what have they said. its look great.
Hey I’ve tried doing the 4 hole injectors and my jeep seemed to have more power with the msd I have installed but it runs really rich
If your engine isn’t pulling timing you’re gonna blow it up putting your intake air temp sensor in your intake box.

Hey Rusty 99 jeep cherokee xj takes two cranks to start any clue, need your help please.
need to first check the fuel pressure also see if the pressure drops after the engine is off sounds like it bleeding off fuel pressure when sitting that the usual with this problem mine did the same it was the injectors on mine the fuel pump has a Che k valve built in that also causes this problem
if you have the engine running and ahut it off and crank right back up does it start fine ?
also any codes
it's probably the starter for months I would have to turn and hold the key for 4ish seconds with the engine trying to turn over but it wouldn't then when I turned the key a second time and it fired right up every time on the second try till one day at a Walmart my Jeep wouldn't do anything at all, hit the starter with a pole and hammer and bam started
if you let your jeep sit for a while a hour or more on a hot day, the fuel still in the injectors after you turn it off will be vaporized. so when you try to start it the first time it is not getting the proper fuel. when you let off then try again it get the amount of fuel required to fire up. it is a typical problem hope that helped a little proud owner of 3 xj
