Hello, I have repaired over 30000 vehicles in my career and I dependence to question you questions before I am not there in person to accumulate facts, data, or to test your vehicle. I may question you to feint breakdown in my stead. If chemical analysis is needed and you would rather not law testing, I can allow 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 approximately the hardship history. It currently has a master tech official idle ventilate run valve and tps installed. without moving anything, the last (used) ecu and my original, would direct in the car without this symptom.
This could be a large vacuum leak ,with the MAF joined it is solitary measuring the expose that is getting next the MAF, consequently if the intake manifold is sucking in expose the expose to fuel ratio will be definitely 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 subsequent to the engine admin and later you hear the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
