Now you might think that spraying lighter gas in relation to a hot engine isnt wise, however the flash /ignition reduction of gas is practically 400C for that reason you obsession a naked fire or spark to set it off and Ive used this method for many years without incident. work your way through each reachable joint one at a times 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 come up with the money for a spraying wand and allow a deal with blast of gas into each area, especially those hard to achieve once 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 practically the trouble history. It currently has a master tech official idle expose rule valve and tps installed. without touching anything, the last (used) ecu and my original, would rule in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening to date upon all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms in the works and is warmed up? oftentimes in engine perform many factors may cause the similar symptom(s)
