Hello, I have repaired exceeding 30000 vehicles in my career and I habit to ask you questions past I am not there in person to hoard facts, data, or to exam your vehicle. I may question you to appear in study in my stead. If scrutiny is needed and you would rather not undertaking 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 tell you a tiny more more or less the trouble history. It currently has a master tech qualified idle ventilate run valve and tps installed. without disturbing anything, the last (used) ecu and my original, would run in the car without this symptom.
This could be a large vacuum leak ,with the MAF joined it is solitary measuring the freshen that is getting behind the MAF, as a result if the intake manifold is sucking in air the ventilate to fuel ratio will be certainly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. as soon as carb cleaner spray can spray in the place of the hissing subsequently the engine dispensation and bearing in mind you hear the engine stall or rev difficult there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
