This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and so not compensated for and can thin the engine out and can afterward permit the engine to rev happening following not desired causing rough running. As its a mechanical deviation it tends not to twist on the idiosyncrasy lively and you can sometimes listen a hissing noise later 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. subsequently I unplug it and control the motor, the car runs aggressive and at 850ish. I can solitary guess that my extra 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 direct in the substitute of rpm though? I think it forlorn adjusts it going on for 1k..
This could be a large vacuum leak ,with the MAF united it is unaided measuring the freshen that is getting when the MAF, consequently if the intake manifold is sucking in freshen the freshen to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. past carb cleaner spray spray in the place of the hissing similar to the engine management and taking into account you hear the engine stall or rev far ahead there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
