sigh... More rough idling
 

Geez I'm ticked. I (well, more Willie, haha) just replaced a whole SLEW of things, including the LIM gasket, the plenum gasket, the PCV valve, etc and it's STILL STILL idling badly. What can cause a car to idle this badly? the cat? bad alternator (because mine's getting there)?

Try cleaning your IAC valve yet?

Pete...can you please link in the other threads regarding this issue so we don't duplicate the questions and items that have already been looked at.

Thanks
