Hello, I have repaired beyond 30000 vehicles in my career and I compulsion to question you questions back I am not there in person to gather facts, data, or to exam your vehicle. I may ask you to accomplishment chemical analysis in my stead. If chemical analysis is needed and you would rather not acquit yourself testing, I can come up with the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. similar to I unplug it and rule the motor, the car runs rude and at 850ish. I can unaided guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much govern in the alternative of rpm though? I think it isolated adjusts it on 1k..
This could be a large vacuum leak ,with the MAF combined it is deserted measuring the ventilate that is getting in the same way as the MAF, therefore if the intake manifold is sucking in ventilate the ventilate to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. as soon as carb cleaner spray can vaporizer in the area of the hissing considering the engine processing and with you listen the engine stall or rev highly developed there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
