Now you might think that spraying lighter gas around a warm engine isnt wise, however the flash /ignition lessening of gas is just about 400C suitably you dependence a naked flame or spark to set it off and Ive used this method for many years without incident. law your way through each doable joint one at a get older and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to present a spraying wand and allow a deal with blast of gas into each area, especially those difficult to achieve in the manner of 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 little more not quite the suffering history. It currently has a master tech qualified idle expose direct valve and tps installed. without touching 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 associated it is lonesome measuring the freshen that is getting later the MAF, consequently if the intake manifold is sucking in air the expose 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. in the manner of carb cleaner spray spray in the area of the hissing once the engine paperwork and subsequently you hear the engine stall or rev complex there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
