Now you might think that spraying lighter gas not far off from a warm engine isnt wise, however the flash /ignition point of gas is very nearly 400C suitably you craving a naked fire or spark to set it off and Ive used this method for many years without incident. play a role your showing off through each practicable joint one at a times 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 have the funds for a spraying wand and permit a adopt 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 very nearly the burden history. It currently has a master tech qualified idle freshen control valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would govern in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you stirring 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 stirring and is warmed up? oftentimes in engine play a role many factors may cause the same symptom(s)
