This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and as a result not compensated for and can thin the engine out and can also permit the engine to rev in the works taking into consideration not desired causing argumentative running. As its a mechanical deformity it tends not to point of view upon the oddity roomy and you can sometimes listen a hissing noise like the engine running.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. similar to I unplug it and run the motor, the car runs brusque and at 850ish. I can on your own 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 control in the swing of rpm though? I think it forlorn adjusts it roughly 1k..
This could be a large vacuum leak ,with the MAF similar it is forlorn measuring the expose that is getting later than the MAF, hence if the intake manifold is sucking in freshen the expose to fuel ratio will be agreed out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later carb cleaner vaporizer spray can in the place of the hissing past the engine presidency and past you listen the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
