1998 JGC won't stay running by bradsdad304

I have a 1998 JGC that was running fine until yesterday. When I tried to start it in the morning the battery was dead so i jumped it with my other car and it started right up, buy as soon as I take my foot off the gas it dies. It will not idle at all. I don't know anything about cars and am hoping someone here will be able to help me figure this out. Oh yeah , it is a 6 cylinder 4X4

1996 Jeep GC will not run by jeepercreepe

I have a 1996 Jeep Grand Cherokee with the 4.0 six. It ran fine. I went out to start it and it turned over but would not run. Didn't even try to run. I can hear the fuel pump working at the tank. Haven't yet checked the spark. I forgot to mention in the earlier post that the guages also don't seem to be working. With the key on the needles don't move, but the indicator lights come on as normal and then go off. Because there was no warning and the guages aren't working I wonder if it is in the electronics. Anyone else have this happen?. Is this a well known happening? Suggestions?

We have a 2000 Grand Cherokee that has an intermitent issue with the engine hesitating and then reving while driving. It mostly happens after extend driving, approx 1 hr. The check engine light comes on and will stay on for a day or so then just go off. Any suggestions on what it might be.

Not too sure, could be cat converter, you can take it to auto zone and they will check the computer or the engine lite issue at no charge and that may give you a better idea. Sounds like it's getting hot then giving you the trouble. Could also be the sensors on your exhaust too. Good luck...Jeff

1996 Jeep Grand Cherokee Stalls/Hard to Restart by cc757

I have a 1996 JGC 4.0 that has started stalling. It has gotten worse in the last 2 weeks. I have replaced the idle air motor, the throttle position sensor. No vacuum leaks, all grounds appear to be good, no corrosion. Going to check the low temp thermostat in cooling sytem, crank postion sensor. I have read some posts where people have taken the PCM computer and sent it out to have it rebuilt. Does anyone know where or who to send this to??? This is driving me nuts.

My mechanic replaced the starter and coil and did not have the problem since.

Thanks bradpans, I just got back from my mechanic's shop and he replaced the temp sensor on top of the H20 pump that talks to the fuel system. I drove the car for about 10 miles. No surging at idle or stalling yet. We may be on to something. I will have him double check the starter and coil again. CC
