Idling

Asked by Feb 29, 2016 at 02:39 PM about the 2007 Chevrolet Impala 1LT

Question type: Maintenance & Repair

Why would my car turn off when its sitting still
idling.

1 Answer

Dirty PCV valve or IAC (idle air control valve). If it runs fine when pressing on the gas I'd swap the IAC first. A good cleaning of the throttle body and MAF/MAP sensor wouldn't hurt either.
