| Iv got a 2001 JGC 4.7l and im having this problem where im getting a error p1686 (skim) but the dealer cant access the computer to reset the system??? Im not sure if i should replace the PCM or skim moduel or if it is the battery??? | |
I have had nearly all of the same problems that most of you have had. Starting, low idle, running rough, and burning rich not passing emissions etc.. I have replaced the idle motor, o2 sensor, map sensor, chased wires, ground wires. up until recently the only code that would show was 52 (extremely rich). After 3 years and at my wits end, I finally decided to replace the PCM. I found one at a junk yard off of a 95. It has been about a week and it seems to have solved the problems (knock on wood). It idles at the proper RPM, better fuel economy, and thus far I haven't had any problems or codes. I hope that this might help others that are having similar problems. Good luck.

I have a 2001 Grand Cherokee that im having starting issues. This has been a intermittent issue. When I turn the key to start it, the dash lights come on but the engine does not turn over or anything. After several attempts to start by turning the ignition it finally will start. No starter drag or anything, a clean sounding start. it does this cold or hot. I checked the Battery and battery cables, they appear to be fine. sometimes it will start the first time, other times it takes 5-10 attempts. Thx for any help.

Ok here is the deal.. I was driving my 2002 JGC to Fl which is about a 5 hr drive from where I live. It is a lot of stopping and going. But after about 4 hours when we would get to a red light it was shaking bad when we were stopped. Now 2 weeks later it is still doing it. We thought maybe we had gotten bad gas. that wasnt the case. If you put it in N while stopped at a red light it is fine it doesnt shake. Also when you start to pull off from the light it hesitates. Please help me!! I just spent 536.00 on a thermometer and a radiator fan.. I would like to come out as cheap as possible.

Replying to: jeepercreepe (Mar 22, 2009 10:36 am) Did you ever figure out what the problem was? I have the exact same problem with my 96 GC 4.0 six. 191000 miles. Mine stopped in the middle of a 4 hour trip by the side of the highway though! To the response from tuggajb, my fuses are straight, would the ignition switch kill the vehicle and the guages while running down the highway? Thanks for any help all.
