Pontiac Grand Prix Stalling Due to Mass Air Flow or Crankshaft Position Sensor Failure

(35 reports)

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

Random stalling while driving and no start for 10 minutes. -
my grand prix has been stalling for weeks now cant seem to find the problem. the mass air flow code keeps popping up and we've changed everything it could be. the code still puts up, this is driving me and my dad crazy we cant figure out anything. were thinking it the computer thats bad but were not sure help plz? -
I had more than just stalling! Once my GTP reached normal operating temp. it would stall at first then completely cut off! not good in rush hour traffic! Once it cooled down, it would start until it warmed back up. I let it sit a few months while I researched the problem. Did a major tune up, changed all fluids, plugs, etc... The problem remained. I was ready to change the CPS, not looking forward to it! Then decided to change the MAF. BINGO! It worked! -
mass air has failed 4 times in 6 months.the shop tells me they replace I have my doubles. -
repeated stalling and check engine light. Diagnostic test coded Mass Air Flow Sensor. Once replaced no more problems -
Car would stall intermittenly.no check engine light car would run for a month or longer without stalling.Would stall at any speed.Mass air flow sensor was the culprit.I tapped lightly on the sensor and the engine stalled!!Try running the car with the sensor unplugged. -
engine occasionally surging... and occasionally stalling CEL reporting high O2 sensor.... replaced ... bad diagnosis True problem was MAF which of course could send rich signals to O2. -
My check engine light came on, and it was due to a MAF sensor. I was getting a new oil change, and the tech told me I should get an engine flush to clean the sensors. It did not work and I was pissed for spending a hundred dollars. -
Stalls after the engine hit normal operating temperature while driving. Replaced the MAF problem no longer exists. -
