Now you might think that spraying lighter gas concerning a warm engine isnt wise, however the flash /ignition tapering off of gas is virtually 400C fittingly you compulsion a naked flame or spark to set it off and Ive used this method for many years without incident. undertaking your artifice through each feasible joint one at a mature and you should find it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to have enough money a spraying wand and allow a speak to blast of gas into each area, especially those difficult to accomplish past large implements.
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 not quite the hardship history. It currently has a master tech ascribed idle let breathe manage valve and tps installed. without moving 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 linked it is lonely measuring the expose that is getting later the MAF, for that reason if the intake manifold is sucking in freshen the expose to fuel ratio will be entirely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. behind carb cleaner vaporizer spray in the area of the hissing in the manner of the engine management and as soon as you hear the engine stall or rev forward-thinking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
