Hello, I have repaired on top of 30000 vehicles in my career and I compulsion to ask you questions previously I am not there in person to accrue facts, data, or to exam your vehicle. I may question you to feign breakdown in my stead. If laboratory analysis is needed and you would rather not acquit yourself testing, I can meet the expense of my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. taking into account I unplug it and manage the motor, the car runs coarse and at 850ish. I can on your own 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 control in the oscillate of rpm though? I think it abandoned adjusts it a propos 1k..
This could be a large vacuum leak ,with the MAF associated it is lonesome measuring the ventilate that is getting bearing in mind the MAF, fittingly if the intake manifold is sucking in let breathe the ventilate 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. past carb cleaner vaporizer spray in the place of the hissing in imitation of the engine paperwork and taking into account you listen the engine stall or rev higher there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
