Question about 2005 Pontiac Grand Prix
I have a 2005 Pontiac Grand Prix with about 100,000 miles on it. I reciently replaced my PVC valve and have started to have an issue where the car when I first start it will buck at idle between 700 and 1400 rpm, until ti warms up a bit where it calms down and idles steady. Then when I take off in the the car it the tach will rev up then fall and stall out the car even though I am doing 30mph+.
Other than the PVC valve, we have also replaced the Primary solenoid for the secondary AIR system, the AIR pump, and the Secondary solenoid for the secondary AIR system to clear other codes that were happening on the car.
Any help would be appreciated.
