Hello, I have repaired over 30000 vehicles in my career and I habit to question you questions back I am not there in person to collect facts, data, or to exam your vehicle. I may ask you to bill psychiatry in my stead. If psychiatry is needed and you would rather not conduct yourself testing, I can provide 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 virtually the trouble history. It currently has a master tech recognized idle let breathe manage valve and tps installed. without disturbing anything, the last (used) ecu and my original, would control in the car without this symptom.
This could be a large vacuum leak ,with the MAF connected it is by yourself measuring the let breathe that is getting later than the MAF, appropriately if the intake manifold is sucking in let breathe the air to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. following carb cleaner spray can spray can in the place of the hissing following the engine running and once you listen the engine stall or rev sophisticated there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
