Now my jeep is a 1994 so my ECU not nearly as complicated. I had very similar issues but I never got a code for my MAP sensor (even though OBD1 I still should have) I was just throwing parts at it left and right. Got so tired of it even took it to a shop. They guessed crank sensor. Still...

Thank you, I now see its all used, I might as well just clean mine up then and reuse them. The automotive tape is an awesome idea, thanks! I think I may try that to just clean them up and use automotive tape on them

My 1994 XJ has that lower door panel rubber mat that runs the length of the jeep on the outside. A few stops its coming off. I have tried to take 3M adhesive and reseal it on but starts to get lose after a few months. Plus its starting to get a bit wavy. Anyone know its exact term its called? As...

Shocks are the N2.0 rough country 2-4 inch lift ones. And yes I have been doing wheeling for years ( since 2007! lol ) with it still connected. In NJ most times am just in sand pits and hasn't been terrible but its becoming annoying on bumpy trails with it still connected lol.

Ok, thank you!

When are brake line extensions needed on the XJ? I ask as I have a 3 inch lift with 31s. So far for years they have been fine. But I am thinking of putting the front sway bar quick disconnects on for more flex. With a 3 inch lift and front sway bar disconnects will brake line extensions be...

I have a 1994 XJ with 4.0L 4wd automatic 4spd. Am pretty sure my ECM is bad. I pulled it and I am having a hard time knowing which one I have to order one. I can get a new Chrysler one on a black Friday special for under 300 dollars. These are the part numbers show both for 4.0L and are R6027888...

I have a 1994 XJ 4.0L with 181k miles on it and am running into a lot of electrical issues lately. Most if it comes down to corrosion in the wiring harness connectors. I have found MAP sensor connectors and a few other connectors new. But having issues finding like the fuel injector connectors...

It did turn out to be the alternator. It is odd, unless something in the harness got disturbed and its working now (hopefully not the case). But I bought a new alternator and jeep fired right up, guess old one had a short in it? Its holding at 14V on the gauge. Last time a few years ago I got a...

Thanks guys for every ones ideas, So I now had a starting point with every ones suggestions. I believe its the alternator as I took off the alternator plug (4 bolts) and it started right up then. Put the harnesses back on, its dead and wont start. So I am not double guessing myself, my...

I have a 1994 XJ with 180K miles 4.0L automatic. I am stumped on this one. Battery has 12V (confirmed from mulimeter) and all the lights are on the jeep when doors are open. 80 percent of the time put the key in the ignition and turn it forward and nothing. No gauges, no radio, no start. The...

My jeep gauge says I have been running 210-220 last few months. In 6 years of owning it, never ran that hot since I installed a 2 row radiator. Now I have replaced most everything with OEM dealership parts, hoses, thermostat, radiator cap, and have a high flow Hesco thermostat housing. Even...

Thank you, will buy some tonight and try it

I have a 1994 jeep cherokee with the 4.0L. Has 180K miles on it. This winter it started to run lean. Found had 2 leaking injectors and a bad fuel pressure regulator. Replaced them plus the spark plugs. Have an over heating issue now and have a 2 row radiator that has less then 15K on it and a...

I may have made a mistake a few years ago, I put on Ford 19 lbs 4 point fuel injectors on my 1994 4.0L. I have an adjustable fuel pressure regulator. I was told by my friend they are 49 PSI injectors. So years ago I set my adjustable fuel pressure regulator to 49 PSI. After a few years of having...

Thank you

I have tested my MAP sensor and it is bad. I have to get a new one. Is MAP sensor one of those sensors need to buy Chrysler/Mopar replacement or is it ok to get the cheaper aftermarket from advance auto? Like I know the engine temp sensor that is in the thermostat doesn't not work well with...

Thank you guys! I never associated the IAC on the TB as it controls the idle, I always thought the TB position sensor did that and thought the IAC was part of the cruise control system lol . I will play with it and clean it later on, thanks again!

Tonight out of random luck a new symptom which it has never done before. In idle, if you just tap the gas idle jumps from 800 rpms to like 1500 for like 3-5 seconds then goes back down to 800.

I need some help please. My XJ is driving me crazy again. Its a 1994 XJ, 4.0L, 4wd, automatic AW4, with 177K miles. When Jeep is cold and gets started up after sitting for several hours idles fine runs fine then maybe a mile later if at a stop light it just stalls. 95 percent of time starts...
