Hello, I have repaired beyond 30000 vehicles in my career and I dependence to ask you questions in the past I am not there in person to pile up facts, data, or to exam your vehicle. I may ask you to feat examination in my stead. If chemical analysis is needed and you would rather not take action testing, I can pay 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 burden history. It currently has a master tech official idle ventilate govern valve and tps installed. without disturbing 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 similar it is solitary measuring the expose that is getting subsequently the MAF, in view of that if the intake manifold is sucking in expose the ventilate to fuel ratio will be no question 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 spray can in the area of the hissing in the same way as the engine running and as soon as you listen the engine stall or rev complex there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
