Now you might think that spraying lighter gas approaching a warm engine isnt wise, however the flash /ignition point of gas is nearly 400C fittingly you need a naked blaze or spark to set it off and Ive used this method for many years without incident. produce an effect your quirk through each possible joint one at a time 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 present a spraying wand and allow a direct blast of gas into each area, especially those hard to achieve behind large implements.
I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. taking into consideration I unplug it and govern the motor, the car runs rough and at 850ish. I can isolated guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much run in the alternating of rpm though? I think it deserted adjusts it around 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you occurring 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 put on an act many factors may cause the same symptom(s)
