Stalling Due to Mass Air Flow or Crankshaft Position Sensor Failure on Chevrolet Impala

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 hear air hissing when I lift the hood. When I move the hose I can hear the air coming from under the hose. My car cuts off and stall wen I come to complete stop. Sometimes when I'm slowing down to come to a stop it cuts off. I need help!!!

My car would crank but I had to keep my foot on the gas to stay crunk. I disconnect the MAF (Mass Air Flow)and it stayed crunk with no assistance. I replaced the MAF for $138 from autozone and have been driving for 2 months now with no issues.

Cars stalls and does not start back up, unless I wait ten minutes or more. Stalls at least three times a day. I tried replacing the Mass Air flow sensor; yet, the problem continues.

car starts up fine... but once the temp reach norm 180 degrees and u shut car off it doesn't want to start right . car will stall & hesitate trying to start back up. unless engine completely cools all the way down. If u let car idle and run at norm operating temp you'll notice the car running rough at idle and the check engine light will come on.

My 3.8 impala stalled twice while my wife was driving. Like clockwork, it would shut down when it got to normal operating temp (about 175 per the temp gauge). There were no codes and no check engine light. I changed the crank position sensor and the problem didn't go away. I then unplugged the mass air flow sensor, and the car would run (not real well, but it would run and idle). Unplugging the MAF causes the computer to rely on other sensors to operate. Wish I would have changed the MAF first, because it was MUCH easier to do than the crank position sensor.

Our son's 2001 Chev Impala 3.4L V6 stalls in normal weather and when the weather is damp or rainy the engine runs very rough, misses and backfires. The vehicle also has failed the emissions test. The emissions report stated the possible failure was due to a faulty Crankshaft Position Sensor and or Catalytic converter. I have replaced the Crankshaft Position Sensor but the vehicle still stalls and runs very rough when the weather is damp or rainy. We had a new Catalytic converter installed before the emissions test.

I currently have this issue, went to autozone and ran diagnostics to see engine code p0102 which deals with the MAF Sensor.
