Question about Pontiac Grand Am

1 Answer

Hello, My 1999 Pontiac Grand Am starts but does not move when you step on the gas. It's kind of a rough idling. I heard it could be a few things, head, or 1st cylinder? What do you think? And how much to fix it?

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.

Rough idling in a 1999 Grand Prix GTP


If this problem doesn't happen every time i would not only change plugs but wires as well.The wires can move if they are loose or even heat damaged and interrupt the spark. If this doesn't help it sure won't hurt. Next look at the oxygen sensor and change the pcv valve. Then i would move unto cleaning/replacing the MAF sensor and possibly the throttle position sensor too. It sounds like you need a good tune up thats all.

Rough Idle and then the veh cuts off


Have you tried cleaning the mass air flow sensor ? Use Qtip and carb cleaner to remove any gunk on the two wires that strech across the inside.
