This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and correspondingly not compensated for and can lean the engine out and can afterward allow the engine to rev in the works as soon as not desired causing unfriendly running. As its a mechanical irregularity it tends not to aim upon the deviation roomy and you can sometimes hear a hissing noise in the same way as the engine running.
I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. in the manner of I unplug it and govern the motor, the car runs rough and at 850ish. I can only guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much control in the rotate of rpm though? I think it isolated adjusts it in the region of 1k..
This could be a large vacuum leak ,with the MAF linked it is deserted measuring the expose that is getting like the MAF, consequently if the intake manifold is sucking in ventilate the expose to fuel ratio will be enormously out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. following carb cleaner spray can spray in the area of the hissing like the engine running and considering you hear the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
