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.

    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!

    repeated stalling and check engine light. Diagnostic test coded Mass Air Flow Sensor. Once replaced no more problems

  • 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.
