Hello, I have repaired higher than 30000 vehicles in my career and I habit to ask you questions past I am not there in person to stockpile facts, data, or to test your vehicle. I may ask you to work investigation in my stead. If assay is needed and you would rather not operate testing, I can have the funds for my best advice, Fuel pressure?

I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. when I unplug it and direct the motor, the car runs rude and at 850ish. I can unaccompanied 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 every this. I don't think the tps has that much rule in the stand-in of rpm though? I think it only adjusts it with reference to 1k..
This could be a large vacuum leak ,with the MAF amalgamated it is and no-one else measuring the air that is getting with the MAF, fittingly if the intake manifold is sucking in freshen the ventilate to fuel ratio will be entirely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. in imitation of carb cleaner spray can vaporizer in the place of the hissing as soon as the engine processing and as soon as you hear the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
