Good evening,
2000 Impala intermittently running rough. When you hit the pedal to the floor, it may miss, surge, no backfiring. Stopped at a red light may shudder and engine stall. This is intermittent. Not predictable. I eventually had the Service Engine Light (MIL) come on and received a Code for Mass Air Flow Sensor. This car has 188000 kms on it. Does the symptoms I indicate above sound like a Mass Air Flow Sensor, or is it possible something else could be making it look that way. The Sensor is about $200.00 so I dont want to buy one too quickly, that is without getting an opinion from guys in this group...Is is common for these sensors to go. If I do replace it, is there other maintenance I should be doing like pulling the throttle body and cleaning everything....
