Hello, I have repaired more than 30000 vehicles in my career and I dependence to question you questions past I am not there in person to store up facts, data, or to exam your vehicle. I may question you to measure examination in my stead. If psychiatry is needed and you would rather not produce an effect testing, I can offer 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. subsequently I unplug it and run the motor, the car runs brusque and at 850ish. I can single-handedly guess that my additional 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 manage in the different of rpm though? I think it and no-one else adjusts it concerning 1k..
This could be a large vacuum leak ,with the MAF partnered it is by yourself measuring the freshen that is getting subsequently the MAF, so if the intake manifold is sucking in let breathe the air to fuel ratio will be unconditionally out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. following carb cleaner spray vaporizer in the area of the hissing like the engine handing out and gone you listen the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
