i would say do a compression test. u might not be running on all 4. then try a leak down test. check to see if any vacum lines are not rite. and also check your fuel.

good luck

It could be any number of things. Go to vfaq.com under the intake section you will find how to check the ISC. If that doesn't work just look around that site you probably will be able to narrow down your problem. Just remember when your car isn't running right vfaq.com can be your best friend

Factory idle is 750rpm not 1000rpm.
Check for boost leaks, diagnose the ISC, Set your idle to the correct level or a little higher. Is your bov vented to the atmosphere?

As mentioned, go to the VFAQ to figure out if the ISC is any good.

You can adjust your idle with the BISS (screw on top of throttle body (might still have a cap over it if you are luckier than I)). Turning it out (left) will bring up your RPMs.

I had a similar problem a few weeks ago, but my ISC checked out OK. I adjusted the BISS to bring up the idle slightly for a temporary fix, then replaced a worn rubber o-ring on it and cleaned the throttle body. That seems to have fixed my problem.

try cleaning the PCV unit if they these cars have it. But from my work with mitsubishi and crysler cars they all run into that problem. Not the same vehical but my moms plymouth vouager had that problem. when it was runnin you'd have to have the gas on and while movin if you let of the gas it'd sound like it wants to stall so i'd first go w/that. good luck man
