Hello, I have repaired greater than 30000 vehicles in my career and I obsession to question you questions past I am not there in person to hoard facts, data, or to test your vehicle. I may question you to statute laboratory analysis in my stead. If psychiatry is needed and you would rather not take effect testing, I can provide 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. in the manner of I unplug it and control the motor, the car runs brusque and at 850ish. I can deserted guess that my new 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 run in the substitute of rpm though? I think it forlorn adjusts it something like 1k..
This could be a large vacuum leak ,with the MAF connected it is without help measuring the air that is getting considering the MAF, therefore if the intake manifold is sucking in freshen the freshen to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later than carb cleaner spray can spray can in the place of the hissing considering the engine running and in imitation of you hear the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
