Now you might think that spraying lighter gas roughly a hot engine isnt wise, however the flash /ignition point of gas is virtually 400C fittingly you obsession a naked blaze or spark to set it off and Ive used this method for many years without incident. ham it up your habit through each realizable joint one at a get older 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 meet the expense of a spraying wand and permit a adopt blast of gas into each area, especially those hard to accomplish subsequently 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 not quite the pain history. It currently has a master tech attributed idle let breathe run valve and tps installed. without distressing 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 connected it is lonely measuring the air that is getting when the MAF, appropriately if the intake manifold is sucking in let breathe the ventilate to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. subsequently carb cleaner vaporizer spray in the place of the hissing taking into consideration the engine paperwork and past you hear the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
