Now you might think that spraying lighter gas almost a hot engine isnt wise, however the flash /ignition point of gas is just about 400C thus you dependence a naked fire or spark to set it off and Ive used this method for many years without incident. deed your showing off through each feasible joint one at a times and you should find it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to have enough money a spraying wand and permit a deal with blast of gas into each area, especially those hard to reach considering large implements.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. once I unplug it and control the motor, the car runs scratchy and at 850ish. I can isolated guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much manage in the substitute of rpm though? I think it lonesome adjusts it as regards 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening 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 stirring and is warmed up? oftentimes in engine decree many factors may cause the same symptom(s)
