Now you might think that spraying lighter gas a propos a hot engine isnt wise, however the flash /ignition reduction of gas is more or less 400C so you obsession a naked fire or spark to set it off and Ive used this method for many years without incident. show your showing off through each realistic joint one at a epoch and you should locate it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to allow a spraying wand and allow a take up blast of gas into each area, especially those hard to reach considering large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a tiny more about the hardship history. It currently has a master tech endorsed idle expose direct valve and tps installed. without upsetting anything, the last (used) ecu and my original, would manage in the car without this symptom.
This could be a large vacuum leak ,with the MAF amalgamated it is single-handedly measuring the expose that is getting in the manner of the MAF, thus if the intake manifold is sucking in air the expose to fuel ratio will be completely 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 taking into consideration the engine running and with you hear the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
