Pontiac Grand Prix GTP Problem Report
Pontiac Grand Prix GTP Stalling Due to Mass Air Flow or Crankshaft Position Sensor Failure
The car was cutting off while driving it. It won't restart except after 90 minutes or so. I took it to a shop and they advised me to take it to the dealership because the spark plugs were black and "massive oil leak" was noticeable.... However, I also asked the shop to discard some oil because they had put a little too much oil when the car had had an oil change about a month ago. Researching the internet, I decided to unplug the Mass Air Flow Sensor, as advised in one forum. The car ran perfectly fine with the sensor unplugged. I've just replaced it this morning. No more cutting off. Just a little rough idle probably because the car needs a little time to get adjusted to the new $145 sensor from Pep Boys? - ketzazu
Car will starts but dies after 2 or 3 seconds. I've already replaced both fuel pump relays and fuel pump resistor. Car usually cranks and run fine after I let cool down a few hours later. - wimberlyh
Car begins to idle irratically and then will stall after I have been driving it for 20 minutes and it is warm to hot outside. Mostly happens when at a stoplight. So far will start up right away. - Visitor
