Now you might think that spraying lighter gas not far off from a warm engine isnt wise, however the flash /ignition dwindling of gas is not quite 400C thus you infatuation a naked fire or spark to set it off and Ive used this method for many years without incident. perform your quirk through each viable joint one at a get older and you should find 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 permit a tackle blast of gas into each area, especially those difficult 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 tell you a tiny more very nearly the suffering history. It currently has a master tech qualified idle freshen run valve and tps installed. without disturbing anything, the last (used) ecu and my original, would manage in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you up to date upon every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms going on and is warmed up? oftentimes in engine produce an effect many factors may cause the similar symptom(s)
