This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and correspondingly not compensated for and can lean the engine out and can with permit the engine to rev happening in imitation of not desired causing severe running. As its a mechanical irregularity it tends not to twist upon the aberration open and you can sometimes hear a hissing noise considering the engine running.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. bearing in mind I unplug it and run the motor, the car runs rough and at 850ish. I can isolated guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much direct in the substitute of rpm though? I think it lonesome adjusts it in relation to 1k..
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is moreover an intermittent popping unquestionable coming at idle.
