Read my posting re. the below thread.

Did you read the linked thread above? This forum has tons of info if you spend a minute looking for it. You'll often find a solution faster that way than if you post and wait for someone to spoon feed it to you.

 

If you cleaned throttle bodies, MAF, etc, and still didn't fix this, look for vacuum leaks in the plenum where the engine cover screws go in. If the engine cover is off put the screws back in and see if that fixes the issue. If not, look for holes in those weird little attached "chambers" on the intakes - mine rotted out causing some vacuum leaks and weird idle jumps. Look on both the driver's and passenger side intakes.

 

This thread is over two years old.

It is amazing to me that so many post their problems here after spending $$$ and throwing parts at a problem rather than have a dealer hook up the Consult lll diagnostic tool and pay the diagnostic fee.
There are so many electrical sensors and connections thru the wiring harness that are next to impossible to diagnose without the computer software that the Consult tool uses.
