Question about 2001 Pontiac Grand Prix
I have a 2001 gp gt and after I put a new battery in it the car runs at a low very erratic idle speed used to run about 1000rpm now wavers between 7 and 800. When I come to a stop it idles so low that the engine just shuts down and other times going down the highway it will stop accelerating and slow down then with my foot still on the gas it will catch and speed back up again or just shut down. Any input would be greatly appreciated
The best solution is to do a complete tune up with new spark plugs, wires, fuel filter, air filter, pcv valve and oil change.. If this still happen I would get some fuel injector cleaner, or use marvel mystery oil in both your oil(crankcase) and gas tank. You can get mystery oil at walmart..its in a red bottle with black label.
