Hello, I have repaired over 30000 vehicles in my career and I habit to question you questions previously I am not there in person to assemble facts, data, or to exam your vehicle. I may question you to statute scrutiny in my stead. If examination is needed and you would rather not pretend testing, I can provide 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 tell you a little more practically the problem history. It currently has a master tech attributed idle air rule valve and tps installed. without moving 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 by yourself measuring the expose that is getting bearing in mind the MAF, consequently if the intake manifold is sucking in air the expose 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. taking into account carb cleaner vaporizer spray can in the area of the hissing gone the engine government and once you listen the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
