Re: Air flow issue - 99 Pontiac Grand Prix GT
What system do you have? Manual/auto/dual?
there are different systems used....some have a vac switch in the control head....some have a vac sol box....some have a programmer.....some have a vac tank...the first thing you have to do, is check for vac, at either one of these points, with the car running.....if no vac is present, than something is open between there and the intake........
