  2. JK Wrangler Technical Forum
    I've read many threads with issues similar to mine, just figured I'd put my experience out there. Symptoms: Randomly, at idle, the car gently shakes (rough idle) with rpms hovering around 900-1000 rather than the usual 600-700 Rarely, at idle the engine will just stall, either backing up or at...

    1995 4.0 with a 1993 swapped engine other than that everything is the same(feel like i should mention that) So my idle cold in the morning will sit at the line below the 1000rpm (700-800ish) however once it starts warming up the idle will slowly drop along with the rise in engine temperature...

    I have a 2008 Wrangler X, 2 door with 115,000 miles on it. Six months ago I began having misfires and a rough idle in my jeep. The check engine light eventually came on and and the misfires became constant. Took it to my mechanic and he found that fuel injector 3 was blown. He replaced it...
  10. Engines & Drivetrain
    Hello everyone. I'm new to JeepForum so thanks in advance for your help. I have a 1996 Cherokee 4WD L6 and I think my engine is running a little rich. It used to show the check engine light with a code for fuel air ratio problem. That has since magically disappeared, but my engine still idles...
  11. TJ Wrangler Technical Forum
    Hey everyone, My 1999 2.5L auto TJ is exhibiting poor acceleration at approximately 40mph/3500 RPM. Seems like it is stuttering when I floor it and has little blips at idle, I can't think of how to explain the sound of either. I can't get past 40 mph. It was occasionally stalling at idle...

    I have a 2011 2dr jk. I did a tune up on it this weekend changing sparking plugs, wires and ignition coil. I double checked all the spark plug gaps, made sure the wires were connected properly to the spark plug and ignition coil and in the right order. Now it idles rough and when i drive and...
  13. ZJ Grand Cherokee Forum
    I've had my jeep sitting for about 3 months while it was being worked on (no engine work) and I went to start it and it seemed fine at first. Then there was a horrid burning smell and a plume of white smoke coming from the tail pipe. I pulled it out of the garage to the outside where it was...

    Hello, I am new to the forum and this is my first time posting, but I have spent dozens of hours scouring every forum I can find for an answer to the issue I have, but this is proving a hard nut to crack...

  15. WK Grand Cherokee & XK Commander Forum
    Hey guys, Last year I purchased a 2005 5.7L v8 Grand limited, drove great for about 4 months and then popped the P0205 and another code related to spark plugs. The vehicle started to idle rough and accelerate rough at points with a lack in power and the fuel consumption went through the roof. I...
  16. Engines & Drivetrain
    Okay, so i recently had my check engine light come on, i hooked my scanner up and it showed P0132. So i ordered a NTK Upstream Oxygen Sensor and replaced it. At the same time, I went ahead and took off the throttle body and cleaned the IAC and throttle body itself. I cleared the code and took it...
  17. YJ Wrangler Technical Forum
    Hey guys. It's been a while since I was last here asking for the blessing of the Jeep gods. I looked through some of the older rough idle posts and none of them really describes the problem I'm having exactly, but I got some tips of what to look at next. Here's the scoop: Started the Jeep this...
  18. Engines & Drivetrain
    Hello all, I recently changed some gaskets and when I put everything back together the engine had a rough idle and when in drive it wouldn't accelerate. I had 3 different error codes. P0123 P02111 (forgot the last). The issue was the TPS (throttle position sensor) was slightly unplugged. A...
  19. KJ Liberty Forum
    I have an 02 Jeep Liberty Sport 4WD 3.7 that seems to be devouring very good mechanics (0 for 6). With warm engine, whenever I come to a stop, the RPM’s drop to about 500 then surge to about 1300 and then engine dies. Occasionally it surges multiple times before dying. Shifting to neutral...
