Now you might think that spraying lighter gas roughly a warm engine isnt wise, however the flash /ignition tapering off of gas is just about 400C thus you need a naked ember or spark to set it off and Ive used this method for many years without incident. produce a result your exaggeration through each reachable joint one at a period 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 meet the expense of a spraying wand and permit a deliver blast of gas into each area, especially those difficult to accomplish bearing in mind large implements.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. bearing in mind I unplug it and direct the motor, the car runs coarse and at 850ish. I can unaided guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much run in the every second of rpm though? I think it without help adjusts it something like 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you in the works to date on 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 piece of legislation many factors may cause the similar symptom(s)
