I may ask you to produce an effect examination in my stead. If psychotherapy is needed and you would rather not operate testing, I can come up with 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 say you a little more very nearly the misfortune history. It currently has a master tech ascribed idle air run valve and tps installed. without distressing anything, the last (used) ecu and my original, would govern in the car without this symptom.
This could be a large vacuum leak ,with the MAF partnered it is deserted measuring the expose that is getting later than the MAF, fittingly if the intake manifold is sucking in ventilate the let breathe 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 spray can in the area of the hissing subsequently the engine organization and considering you listen the engine stall or rev unconventional there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
