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

(59 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.

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. -
Engine stalls randomly when turning right mostly or when stopped too long. -
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!!! -
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. -
Won't start at times left alone for about 15-20 mins then it starts up -
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. -
It would stall at stop signs, going 65mph and replaced CPS, and so far so good. -
car stalls out while driving, will not restart until engine has cooled. -
Still have the problem but is not an issue in the cold weather( winter ) -
I changed my.mass air flow system and throttle sencer and my car still stalls to get gas what am I dping wrong y my car won't accelerate as normal -
Car tends to cut off only when turning right at low speeds and I have to push the throttle down during starting for ti to start. Already replaced MAF 2 coils and a iacv -
Stalling at red lights or driving. Auto zone scanned me car for me and I replaced all of the parts and now it runs like new -
Stall while driving , turns over but won't stay running -
Cranks but dies after warming up. Have replace 2x MAF, coolant sensor, Cam position sensor,PCM and cleaned MAF/throttle body. Still have issue. Just unplugged the MAF and it didnt die. Well I guess im on to my third MAF sensor -
In warm weather while driving the car will stall like it is shutting down but never fully quits. Oddly enough it does NOT do this in cold weather! No one can figure out wha t is causing this. When the car is hooked up to a machine....it shows nothing wrong. Any suggestions would be greatly appreciated. -
I have a 2006 Chevy Impala and I've change the er sensor, camshaft sensor and the mass flow sensor, and the catalytic converter. I'm still getting that hestation and the check engine light is on. Took it back to my mechanic and he put the dignositic machine on and now it readering a camshaft timing needs to be replace. This is very upsetting to keep putting work into a car that you can't enjoy riding with worry if it gonna quit on you. I hope after change this, the problem will be resolved. -
This did have an recall. But the key gets stuck in the switch -
car would just die for no reson. You could be going 20 miles or 60. Had to change the mass air flow sensor after trying everything else. -
