Hello all,
I am new here, but have owned 3 XJ's. Great vehicles, and loved all of them.
My 1995 sport is having a problem that I can't figure out, and I need some advice.
The Jeep idle's very rough (although not all the time sometimes its totally smooth)
Here is a list of whats been done.
1. cap, rotor, plugs, wires
2. throttle body removed and cleaned.
3. new fuel injector, checked all, only one was bad.
3. new idle air control sensor ( on the throttle body)
4. vacuum lines checked for cracks ( replaced where necessary)
5. compression test. 110 on 5 cyls and 85 on the #1 cyl ( typical for 190,000 mile jeep)
6. New 02 sensor.
7. endless bottles of chevron techtron LOL
I am when it is idling rough, i noticed that it smells very rich ( like fuel) I am really wondering if the PCM is malfunctioning. Sometimes the car wont start unless I feather the gas pedal.
The neutral safety switch is bad, but when it malfunctions, I just but the car in neutral and it starts right up. Could this be affecting the idle? I don't really think so.
Thanks for any/ all help,
Trevor
