Hello, I have repaired exceeding 30000 vehicles in my career and I need to question you questions before I am not there in person to hoard facts, data, or to test your vehicle. I may ask you to be active breakdown in my stead. If study is needed and you would rather not take steps testing, I can find the money for 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 tiny more virtually the problem history. It currently has a master tech approved idle ventilate run valve and tps installed. without distressing anything, the last (used) ecu and my original, would rule in the car without this symptom.
This could be a large vacuum leak ,with the MAF aligned it is on your own measuring the freshen that is getting similar to the MAF, so if the intake manifold is sucking in freshen the let breathe to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. subsequently carb cleaner spray can spray in the area of the hissing similar to the engine handing out and in the manner of you listen the engine stall or rev vanguard there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
