#92 of 1068 idle problems by rdkljeep98

Jul 25, 2007 (6:03 pm)

hello all, i have a curious problem that i have been experiencing lately with my 1998 Jeep Grand Cherokee, its a straight six and i bought it about 4 or 5 months back. When i put it in gear it intermittenly loses power, i can push my foot down on the gas pedal, and nothing happens. The jeep still is running but it just doesnt respond to the gas being applied, but (and this is where it gets a bit curious) if im stopped at a stop sign or a light while its still in drive but my foot on the brake, the jeep will begin revving and if i let off the brake a bit, it will not just roll but lurch forward as if a good amount of gas was applied while my foot isnt even near the gas pedal. also while driving, and experiencing the loss of power popping sounds can be heard from under the hood. the rpm needle jumps up and down the whole time this is going on as well, and the engine runs like garbage when its in park and this is happening. On a whim, we changed the crank sensor thinking it might be somehow related, but that didnt do it. does anyone out there have any possible ideas that could help? anything would be appreciated

i would try a new distrubrater inside it it has a cam sensor that is used in relation to crank sensor by the computer and also the soloinides in the trans

#95 of 1068 My 1994 Jeep Grand Cherokee (L6 4.0 liter) keeps stalling by naxan90027

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?
 
Thanks.

#97 of 1068 2002 JGC Laredo....multitude of problems by jeepster13

Aug 23, 2007 (5:26 pm)

Hey, all.....
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 1068 high and low idling, especially when raining by finster2

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 1068 1998 JGC ECM Problem?? HELP!! by maria504

Aug 29, 2007 (7:16 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....
