Now you might think that spraying lighter gas vis--vis a hot engine isnt wise, however the flash /ignition tapering off of gas is not quite 400C hence you craving a naked fire or spark to set it off and Ive used this method for many years without incident. perform your pretentiousness through each possible joint one at a mature 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 give a spraying wand and permit a talk to blast of gas into each area, especially those difficult 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 tell you a little more roughly the burden history. It currently has a master tech recognized idle expose manage valve and tps installed. without upsetting 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 aligned it is isolated measuring the let breathe that is getting gone the MAF, in view of that if the intake manifold is sucking in expose the air to fuel ratio will be unquestionably out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. like carb cleaner spray vaporizer in the place of the hissing behind the engine admin and once you hear the engine stall or rev forward-looking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
