Hello, I have repaired more than 30000 vehicles in my career and I dependence to ask you questions before I am not there in person to pile up facts, data, or to exam your vehicle. I may ask you to deed psychoanalysis in my stead. If breakdown 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 on the air flow meter and said it was good. subsequent to I unplug it and run the motor, the car runs rude and at 850ish. I can forlorn guess that my further 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 govern in the vary of rpm though? I think it isolated adjusts it regarding 1k..
This could be a large vacuum leak ,with the MAF linked it is by yourself measuring the air that is getting later than the MAF, hence if the intake manifold is sucking in freshen the air to fuel ratio will be utterly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. next carb cleaner spray spray can in the place of the hissing bearing in mind the engine processing and once you listen the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
