I put in one shop Mechanic charged for fuel tank 750.00. Found out later it need a crank sensor, not only one but two by two different mechanics. In the mean time car continues to cut off in traffic or wherever. Car goes to another dealer he continue to run all kinds of test and can't fine the reason the car keeps cutting off. It seems as though when it gets hot it will cut of like it not getting the proper amount of gas flow. Being a woman

I just know how the car reacts. between all the people that have worked on this it is still cutting off. I have

spent over 2,000 dollars trying to keep this car running. This is the only problem it has. Its starts right up no

matter when it cuts off. I will be riding along it cuts off i put it in neutral it starts right off. Help me Please I like

my car. One person had my map sensor on backwards.

Grand Prix GT 3.2L V6

  • 89,000 miles

For months this "phantom problem" has been plaguing my wife and I. We are expecting child and our hospital happens to be nearly an hour away. It all started Christmas morning on my way out to work. I jumped into the car and noticed that I wasn't able to get out of my parking spot due to some ice. I borrowed my father's car (neighbor was an 8th of an inch in front of me and didn't want to hit their truck) and my father-in-law was going to come up with some sand & ash to add some traction. I got a phone call from my wife, she said it sounded like it had backfired. I thought that was odd. Ever since then, for about two month I'd start the car first thing in the morning and it worked fine.. after that, it would back fire, idling really roughly to the point the engine would shut off and the pressure was so great that it blew my vacuum hose off! That has stopped but a new more serious problem has reared it's ugly head; on our way to a prenatal appointment I made a hard left-hand turn and the car DIED! I barely missed a semi-truck! Since then it has died about four times, and every mechanic couldn't establish the problem. After reading another complaint on the website I believe it might be the mass air flow sensor that's causing all of this.. I can't wait to pay this car off so that I can get a new one.. see my other complaints concerning this make/model of car... and GM wonders why it is struggling; perhaps if they made quality cars they wouldn't be in trouble.. mind you I say this because my last car, which also was a Pontiac was also a piece of... work.

All of a sudden one day after starting the car bucked and kicked and wanted to die! It stalled out a few time over an hour. The check engine light did come on upon one of the restarts. Would drive fine then all of a sudden just die!

Dealer reported a blocked / damaged Mass Air Flow Sensor. $ 700 later it was back to normal.... Whatever that is for GM these days.
