Now you might think that spraying lighter gas something like a warm engine isnt wise, however the flash /ignition lessening of gas is just about 400C consequently you habit a naked flame or spark to set it off and Ive used this method for many years without incident. play a role your pretentiousness through each doable joint one at a become old and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to pay for a spraying wand and permit a direct blast of gas into each area, especially those hard to reach in the manner of 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 not quite the difficulty history. It currently has a master tech endorsed idle air direct valve and tps installed. without moving 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 taking place to date on every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms taking place and is warmed up? oftentimes in engine be in many factors may cause the same symptom(s)
