Performed the Sensor gound test (All grounds are clean and tight) Reset the TPS Swapped ECUs (then swapped back) Checked Cap/rotor/wires and plug gaps Swapped to coil (then swapped back) No dice, it acts like more of an ignition problem than fuel related. My Temp gauge reads normal but it sure feels like its awful hot in the engine bay.....excessive heat messing with something? No much left i havent messed with...Coolant temp sensor on the block? Fuel injectors? Never changed the fuel filter... (truck has plenty of power though) Pretty lost here anymore. O Well I'm done for the night, who knows it just might be 1 of those things that fixes itself...

Well after a few miles of driving, the problem is still very visable. Next steps include checking the TPS, swapping ECUs and even swapping Distributors... The joy of having a parts Jeep is the ability to swap parts, ha ha, i know its not the right way to go about diagnostics, but I'm sure to find the culprit of this issue :rotfl2:

Recleaned the C101 connector as well as removed and throughly cleaned the EGR valve and ports. The problem seems to have been deminished a bit but at idle its still missing. Ill put some more miles on it and also check the TPS again this week.

considering all the 91+ XJs/MJs no longer had the CAD system, and just use 1 solid shaft. That should be enough proof that it cause's no harm ;)

This symptom has been around since the purchase of the truck, unknown how long prior... Ill swap the EGR valve with 1 from the parts Jeep and recheck the TPS and grounds tomorrow or early this week. Thanks guys!

When the EGR rod is pulled towards me, the truck gets worse and worse and then stalls out alltogether. (stupid question) Is that how its suppossed to work or have I found my issue? Thanks!

They did a great job "80sing" up my 96 XJ :D

FYI the rear handles on an XJ from the same side will also work on the front of an MJ ;)

Ha Ha. Basically the condition only shows itself under light throttle. If i hammer on it and get it up to speed you don't even notice the issue, but your really gotta lay into it.

Alright, well its late but I figured id see if i could gather up any other thoughts from you guys. The issue lies within "Oscar" an 88 AW4 4.0L. Ever since purchasing it, ive have a "missing" condition at idle and while driving it likes to buck intermittently from around 1200-1750 RPM under light load, kinda while lugging the engine through the shifts... I checked the TPS and even replaced it and the entire throttle body from a parts Jeep. New (less than 1k miles) Plugs/Wires/Cap/Rotor Same for the o2 sensor Ive cleaned up and check over the Ign. coil but have a newer 1 on another truck I'm gonna swap and try out. All Engine and Chassis grounds are clean, refreshed and tight Cleaned and resealed the C101 connector MAP, IAT, and Knock sensors check out ok New Fuel pump installed less than 1k ago I'm beginning to think something with the EGR system might be the culprit here. The truck drives great and has plenty of power under load and minus these two small issues. I just know theres something not quite right... Thanks for any ideas fellas. I have a few other things i can toy with but it never hurts to gather some other opinions ;)

Thanks guys for all the compliments! :D I'm just a Comanche Nut like all of us. :chillin: and Jim as much as I appreciate the offer, I think Walker would get homesick all the way out there :rotfl2:

Here you go: :drool: :drool: :drool: :drool: :drool: :drool: :drool: :drool: Really?. I'm definently not gonna knock it till i see it all finished though ;)

All i can say is, If those lights are going on a truck worthy of those lights....well... I WANNA SEE THE WHOLE TRUCK! :brows:

http://www.ebay.com/itm/NOS-JeeP-Comanc ... 25&vxp=mtr At 9:45pm est this seat of Tail lights was at $536.00usd! :eek: REALLY!? you can probably get a whole truck for that in some parts of the country....UNBELIEVABLE! :nuts: :fool:

Had to swap Radiators this evening, the drain petcock had all but eroded away and was leaking pretty good. O Well ill seal it back up and keep it as a spare. As long as the new 1 lasts me awhile :D

I remember almost crying in school when that truck got destroyed! What an awesome clip though!.....I can't wait to see your truck with all the striping done. any plans for a rollbar and lights? :thumbsup:

:clapping: :clapping: :rotfl2: Nice!

Hope everyone has a great day with family and friends! Also please don't forget about all of Americas heros who can't be home to celebrate with us this 4th of July :USAflag: :cheers:

:rotfl2: :rotfl2: :rotfl2: :rotf: :rotf: That just made my morning!

Yeah, i knew we were all gonna pay for our unusual mild winter come summertime.....its only just beginning, O Well, Bring it on! :cheers:

:thumbsup: Good to hear!

Now that is cool! This thing is turing out great man, keep it up! :thumbsup:

96- flares look great on the 97+ setup.

I'm pretty sure a 235/75 will NOT work on a 10" wide rim. on a stock truck if they have minimal backspacing they will stick out very far. you'd need atleast an 11.50 tire to be able to safely run those. and that means going up to atleast a 33... They sure look nice but on a near stock MJ they sadly wouldnt work.

That was awesome! even my mom thought it was cool :rotfl2:
