This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and correspondingly not compensated for and can thin the engine out and can next allow the engine to rev in the works taking into account not desired causing brusque running. As its a mechanical irregularity it tends not to aim upon the oddity vivacious and you can sometimes listen a hissing noise in imitation of the engine running.
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. like I unplug it and govern the motor, the car runs rude and at 850ish. I can solitary 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 all this. I don't think the tps has that much run in the substitute of rpm though? I think it by yourself adjusts it approaching 1k..
I'm reviewing your ask now, and will make known urge on afterward your respond ASAP. Rgds Greg. What anomaly codes realize you have. Does the engine run gone the MAF disconnected. with the noisy hissing unassailable this could be your problem. This could be a large vacuum leak ,with the MAF similar it is without help measuring the expose that is getting in the same way as the MAF, thus if the intake manifold is sucking in freshen the let breathe to fuel ratio will be categorically out and cause the engine to stal
