Re: runnability problems 02 impala
Sounds like a vac leak somewhere, or an IAC problem, or a fuel problem.....
Vehicle scanned for codes?
Does it run better with the MAF disconnected?
Check for fuel in the vac line to the f/p regulator?
Check for missing o-rings at the PCV....there is a large orange one and a small black one....
This was happening before all these parts were replaced? And still happens?
