Mass Air Flow (MAF) Sensor cleaned while engine on.
I sprayed MAF sensor cleaner into the intake while the car was running. Now it's worst than ever. Will the car
sensor be alright. I first read the can and followed instructions. The car seemed to be operating better, but the
(Check Engine) is still coming on. Then someone told me to spray the sensor while the car's running. Well now
really running bad. Will the (MAF) sensor be OK, say by morning... What are my alternatives otherwise?
Never spray while running, the filaments get hot and will effect the way the computer compensates for the air/fuel mixture and the car won't run correctly. Turn the engine off, clean the MAF again, and let dry completely. Take the negative battery cable off for about 20mins. Then reconnect and start the car, the PCM should be back at the default stage, and the car should run better. Was the CEL on before you did this? If so, scan for codes and don't guess what the issue is.
