Hello. I have a 2005 Grand Cherokee Limited V8 5.7L HEMI. Just recently I noticed that my interior dash lighting had been acting up. The back-lighting behind the heating/ac knobs and all the buttons no longer light up and the back-lighting behind the speedometer-dashboard flicker a lot...

I have a 1989 YJ with 2.5L 4cyl engine. Recently been having weird idle issues. It seems to vary between 1200rpm to 1800rpm. Sometimes got up to 3000, but after a couple seconds, comes back down. Not sure where to start. As I'm a Jeep noob, I would appreciate any help possible.

I have a 2004 unlimited, when driving while going a steady speed I sometimes get a push of power and accelerate even though I didn't hit the gas at all, also when I am driving and let off the gas to go brake or turn my RPMs drop to almost 0 (I have stalled twice my friend helping me diagnose the...

Hello all, I recently got my first Jeep about 3 weeks ago. I traded my motorcycle for it knowing that it would probably need some bit of TLC. It runs perfect except every now and then when I'm making a turn or braking it will die; it doesn't have a slow decline in RPM's, it just dies. The...

I just purchased this 08 JK with the stock 3.8 . I have began experiencing a problem where the engine speed drops and begins running quit rough. When this happens the dash light emits the traction warning symbol, red lighting bolt symbol as well as the engine symbol. The engine does not die. If...

I recently picked up a 97 zj, 4.0, np242.. The truck has not been registered for 7 years, and i believe sat at self storage facility for quite awhile before that.. It is kind of a "franken" truck, as someone at some point basically turned it into a limited, even though the vin# says its a...

I know how frusterating it is to search forums for a problem you're having, only for the OP to not post what actually ended up fixing their problem. So I'm going to post what (hopefully) fixed my erratic and hunting idle. I have a 99 XJ - about 4 months ago, my idle would go up and down when...

Hey guys I was experiencing the dreaded rough idle issue and took advice on how to address the issue. Cleaned the throttle body, replaced with brand new IAC and TPS. Upon startup after installation, my idle was REALLY high. Like 2000 rpm high:confused: it took a minute to settle down and then...

New parts: Campion double platinum plugs Coil pack IAC TPS Fuel injectors O2 sensors (upstream) Battery Thermostat So I'm trying to get this jeep running again since it was stolen and I got it back with no catalytic converter. Everything seems fine aside from this misfire in cylinder two that I...

Hi all, I have a 1998 ZJ with a 4.0L engine. I bought the vehicle about a month ago at around 100,000 miles. The previous owner was a young girl who didn't seem to know much about the car. Anyways she didn't tell me about the problems the car came with. I test drove it and it seemed to drive...

I posted this once before and tried some things but got the same results... My 2001 cherokee sport stalls out when the car is idling. As the engine warms the RPMs drop until the engine runs rough and dies. If I press the gas I can keep it going, and if it stalls it starts right back up so I...

My 2001 cherokee sport stalls out when the car is idling. As the engine warms the RPMs drop until the engine runs rough and dies. I've recently changed the battery, alternator, spark plugs, coil pack, air filter, oil and oil filter, IAC and TPS. I've read on here that the IAC and TPS cans...

I just bought a 97 ZJ on Saturday from a private party. Drove and looked great, had a write-up from a garage giving it a full workover and thumbs up. It's a primarily stock vehicle, former owner put on a push bar and aftermarket fog lamps which are wired to a custom switch mounted inside. There...

Hello all, Here is the problem. I can start my Jeep XJ just fine, though if I do not keep my foot on the gas, it will die. If I keep my foot on the gas for about ~5 minutes and then let go, it will idle, but rough. Things I have done in the past week: - New coolant system. - New battery. - New...

Obligatory background: I changed the oil sending unit awhile ago because I thought it was bad showing sporadic numbers and moving a lot with acceleration/deceleration. It got a little better and less variation. Like I said this was awhile ago and I really didn't think much of it, and more or...

I'm having a strange issue with a newly acquired 99 xj. Its a 4.0 and a auto. It is throwing two codes related to the downstream oxygen sensor, but it runs and drives perfectly fine otherwise. It starts, idles, shifts, drives normally with one exception. If I let off of the gas, and coast in...

So a quick background story: I was wheeling, flooded the engine, engine wouldn't start. Drained water, runs now just with a ticking coming from the engine. Thought it may be the lifters sticking due to water still in oil. After getting ALL of the water out its still ticking. No bent valves/rods...

All, I recently had unsteady idle issues, pulled and cleaned the IAC (with Seafoam), and Seafoamed through the TB. Now, the idle is rock solid. However, I have developed an intense shudder/shaking/vibration. It is noticeable throughout the RPM range, with a significant increase ~1k-2krpm. It...

What's the best brand for a TPS? And which TPS's fit my 2001 4.0 Litre?

Ok, i know i probably screwed something up. I just finished replacing the exhaust manifold on my 99 Cherokee 4.0, which of course meant i had to remove the intake manifold, power steering pump and electric fan to do it. I put everything back together and now when i start the motor it...
