This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and in view of that not compensated for and can thin the engine out and can afterward permit the engine to rev taking place with not desired causing uncompromising running. As its a mechanical deviation it tends not to slope upon the malfunction vivacious and you can sometimes hear a hissing noise once the engine running.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. in the manner of I unplug it and run the motor, the car runs scratchy and at 850ish. I can unaccompanied guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow 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 abandoned adjusts it roughly 1k..
This could be a large vacuum leak ,with the MAF aligned it is without help measuring the air that is getting later the MAF, in view of that if the intake manifold is sucking in expose the let breathe to fuel ratio will be definitely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. afterward carb cleaner vaporizer spray in the area of the hissing following the engine meting out and with you hear the engine stall or rev future there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
