What RPM Does Your 4.0 Idle at

Park

Whoops!

 

700ish idle but the air conditioner has a profound impact on the truck. It jumps all over the place when air kicks on/off. if I am not running air I always see 700 for a warm engine.

I hope this helps.

 

Um hi. I cleaned my MAF today and also took out my k&n setup and cleaned everything also. My van idled at around 700 in park and shoots to about 1000 when ac kicks. That was before i have noticed now that when i start she idles at about 1100 and that is wothout the a/c. And when i am in drive and foot on brake she idles like before around 700. Is this normal or do yiu guys have any suggestions? I am thinking about disconnecting the battery again and see if it will reprogram. But i have no stutter or anything. She is actually running and picking up extremely fast.
