When I let the gas off and my car's idling...it stays around 750rpm. Then a few seconds later, it starts bouncing around. I have the hack and 450's. settings are on -35% across the board. Yes...I've tried different %'s. Any ideas? Thanks

 

check your vaccuum lines for a leak...that happened to me a couple weeks ago, and that was the problem

 

hmmmm.......i will try that. any other suggestions? thanks

 

bump for you.. i want to find out as well.

 

yep, prolly leaking around the where the injectors fit into the intake manifold.
