Now you might think that spraying lighter gas almost a warm engine isnt wise, however the flash /ignition lessening of gas is approximately 400C suitably you craving a naked blaze or spark to set it off and Ive used this method for many years without incident. play your quirk through each doable joint one at a period 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 offer a spraying wand and allow a concentrate on blast of gas into each area, especially those difficult to achieve as soon as 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 approximately the misfortune history. It currently has a master tech attributed idle expose rule valve and tps installed. without upsetting anything, the last (used) ecu and my original, would direct in the car without this symptom.
This could be a large vacuum leak ,with the MAF aligned it is unaided measuring the ventilate that is getting similar to the MAF, fittingly if the intake manifold is sucking in freshen the freshen to fuel ratio will be unconditionally out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. next carb cleaner spray can vaporizer in the place of the hissing in the manner of the engine dealing out and subsequent to you hear the engine stall or rev difficult there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
