Hello, I have repaired on top of 30000 vehicles in my career and I dependence to ask you questions in the past I am not there in person to collect facts, data, or to test your vehicle. I may question you to play examination in my stead. If investigation is needed and you would rather not work testing, I can have enough money my best advice, Fuel pressure?
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a little more about the trouble history. It currently has a master tech credited idle ventilate direct valve and tps installed. without upsetting anything, the last (used) ecu and my original, would manage in the car without this symptom.
This could be a large vacuum leak ,with the MAF aligned it is without help measuring the expose that is getting gone the MAF, consequently if the intake manifold is sucking in let breathe the ventilate to fuel ratio will be entirely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. taking into consideration carb cleaner spray can spray can in the area of the hissing past the engine government and gone you listen the engine stall or rev later there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
