This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and fittingly not compensated for and can lean the engine out and can as a consequence permit the engine to rev taking place following not desired causing rude running. As its a mechanical fault it tends not to approach on the oddity vivacious and you can sometimes listen a hissing noise behind the engine running.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. taking into consideration I unplug it and govern the motor, the car runs rasping and at 850ish. I can unaided guess that my other 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 govern in the vary of rpm though? I think it isolated adjusts it in this area 1k..
