I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. subsequent to I unplug it and direct the motor, the car runs severe and at 850ish. I can lonesome guess that my supplementary 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 rule in the alternative of rpm though? I think it without help adjusts it on the order of 1k..

If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later carb cleaner spray vaporizer in the area of the hissing subsequent to the engine executive and past you hear the engine stall or rev complex there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
