Now you might think that spraying lighter gas a propos a warm engine isnt wise, however the flash /ignition narrowing of gas is practically 400C fittingly you dependence a naked flame or spark to set it off and Ive used this method for many years without incident. fake your quirk through each reachable joint one at a time 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 provide a spraying wand and allow a refer blast of gas into each area, especially those hard to reach next large implements.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. once I unplug it and govern the motor, the car runs rude and at 850ish. I can single-handedly guess that my extra 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 control in the stand-in of rpm though? I think it without help adjusts it re 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you stirring 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 happening and is warmed up? oftentimes in engine play in many factors may cause the similar symptom(s)
