#95 of 1240 My 1994 Jeep Grand Cherokee (L6 4.0 liter) keeps stalling
Aug 15, 2007 (12:30 am)
My 1994 Jeep Grand Cherokee (L6 4.0 liter) keeps stalling. 25% of the time, in runs fine. But usually, it sounds like it fires about 2-3 cylinders per cycle when accelerating and the RPM goes up very slowly and choppy. By this time, if I let go of the gas, It will slowly choke itself. I changed the spark plugs, wires, distributor cap and rotor, fuel filter, fuel pump, and it still remains the same.. I took it to 3 mechanics and they can't figure it out..
But this is my idea, and if you can, tell me if it's a possibility. I used to have a 92 mercury tracer, and a 94 ford ranger. And they both had the same problem. The left blinker would get stuck on the on position, without blinking. And both cars would sometimes die out.. And when i got them fixed, it was the same problem. It was a short in the wiring which killed the fuel pump..
Now, my Jeep keeps reading that there is a rear tail lamp failure and the reverse parking lights do not work, though the fuse is fine and i replaced both bulbs. Could that short possibly be the cause this problem???

I have the same vehicle with what sounds like the same exact problem. It idles really rough (RPMs fluxuating while in park and sounds rough) intermittently on start - up, then upon acceleration chokes, hesitates, and nearly stalls. I haven't heard the popping sound yet. This issue started in the winter about a year and half ago. At first it only seemed to happen when it was cold, but its summer now and happened 3 days in a row. I have had it into the dealership at least a half a dozen times and I don't even know how many things they have checked and/or replaced (fuel system, battery, computer), but have never been able to duplicate or fix the problem and the computer never has any fault codes. I know this doesn't necessarily help you, but reading your post made me feel like I'm not crazy. There are lots of posts out there that seem similar but not exactly the same thing. If I get it fixed or find something I'll let you know, and maybe you could do the same for me?
#97 of 1240 2002 JGC Laredo....multitude of problems
Aug 23, 2007 (4:26 pm)
2002 JGC Laredo with +- 93K....extreme hesitation after stopping...have to keep literally stomping on gas pedal...
very fast idle upon starting in morning, sometimes as high as 3000 RPM...very noisy....had transmission fluid and filter changed out around a month ago, everything seemed fine....trouble started back up about 3 days ago. Also, as I'm driving along, I've noticed a loss of power accompanied by revving of the engine, only fix has been to pump gas until it works its way out....after idle calms down upon starting, I get a shaking,sputtering sensation...almost like it's going to stall out. Finally, my engine light is ALWAYS on, code refers to gas cap/emissions....CANNOT get it cleared.
ANY help is appreciated....taking my Heep to the garage on Saturday....
#98 of 1240 high and low idling, especially when raining

My 2001 Jeep grand cherokee LE starts up fine, does not stall, but the idle raises itself to 3000rpm and down and then up and then down? Please help me before I blow up my jeep [My dealer can not figure it out although it has been there many times with the same problem, they say there is nothing wrong. They just keep saying come and pick it up it is fine and then the same problem occurs. Thanks Liz

#101 of 1240 1998 JGC ECM Problem?? HELP!!
Aug 29, 2007 (6:16 am)
I just bought a used JGC 1998, it has been in the shop more than I had it. I test drove it-loved it-bought it. The next week I had to change the Catalytic Converter, then two weeks after it stalled on me while idle at a light, started right back up with no check engine light on. Mechanic says I need a sensor, I got a Idle Air Control,and two others don't exactly remember the names(he says they are very common on these jeeps. Next day stalls again while driving down the block. Mechanic says IAC sensor is bad so he changed it again. A few days later stalls and hesitant to start while idle again NOW this time it's running really rough and sputters at lights, in traffic. My fuel light came on too and then all of a sudden dissaperaed again. Mechanic says it must be that my jeep only likes parts from the dealer so he changed sensor AGAIN and cleaned fuel injectors!! Still runs crappy,and breaks down at stop sign very rough.
I went to a NEW mechanic, the computer test told him that I need: Ignition Coil, Fuel Pump Relay, and a new computer ECM....TOTAL 762.10 ugghhh...Help what do you think??Sorry so long....
#103 of 1240 2004 Grand Cherokee Near Stall/Idle Rough
Sep 07, 2007 (5:09 am)
I've seen similar posts for this. My 2004 JGC has only 34K on it. It was brought in for diagnosis last week. All they did was reset the computer. The problem persists. I heard rumors that Jeep has issued a fix for this? Anyone know about this or what I can tell the dealer to do since they don't seem to have a good explanation. Seems as though the Pressure control solenoid could be the culprit....
