jeep starting/stalling issues

[sreilly77]

My 1998 Jeep Grand Cherokee with a 4.0L is having starting and stalling problems. No matter whether the engine is cold or warm, when you go to start it, it just cranks. However, if you put your foot on the gas, it starts up. But as soon as you take it off, it shuts right off. But, if I get it running and shift it into any gear right away, it stays running but it idles kind of low. Usually, it idles around 700 RPMS but now when it is in gear and not moving, it idles at about 300 or 400 RPMS. And when I turn the A/C on, it idles even lower. There is no check engine light, but I THINK it is the Idle Air Control valve, but I am not sure. Any help would be great.

Sounds like you need to raise your idle a bit. Was it a slow progression to get to this point?

Well, there was a couple times where I would start the car for the first time and it would just crank. Then immediately after that, I would try again and it would start just fine. But that only happened once in awhile. Also, sometimes I would stop at a red light and it would idle low, but not all the time during a drive. Now I drove it today and it's running perfectly fine. No problems starting it and it is idling perfectly. So I have no idea what happened.

I had the same thing happen to my 04 when the battery started dying. If your gages start to flutter like crazy then it's time to get a new battery.
