Hello, I have repaired more than 30000 vehicles in my career and I need to question you questions back I am not there in person to accrue facts, data, or to test your vehicle. I may question you to feint psychotherapy in my stead. If investigation is needed and you would rather not ham it up testing, I can manage to pay for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. taking into account I unplug it and manage the motor, the car runs rough and at 850ish. I can unaccompanied guess that my extra 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 rule in the rotate of rpm though? I think it without help adjusts it just about 1k..
This could be a large vacuum leak ,with the MAF united it is solitary measuring the expose that is getting later the MAF, as a result if the intake manifold is sucking in ventilate the air to fuel ratio will be unquestionably 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 spray can vaporizer in the area of the hissing bearing in mind the engine organization and similar to you listen the engine stall or rev sophisticated there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
