Hello, I have repaired over 30000 vehicles in my career and I craving to ask you questions in the past I am not there in person to pile up facts, data, or to exam your vehicle. I may question you to work breakdown in my stead. If investigation is needed and you would rather not doing testing, I can allow my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. considering I unplug it and run the motor, the car runs sharp and at 850ish. I can and no-one else guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much govern in the different of rpm though? I think it without help adjusts it re 1k..
This could be a large vacuum leak ,with the MAF similar it is isolated measuring the air that is getting taking into consideration the MAF, as a result if the intake manifold is sucking in air 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. like carb cleaner spray can spray in the place of the hissing later the engine government and in imitation of you hear the engine stall or rev highly developed there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
