Now you might think that spraying lighter gas roughly speaking a hot engine isnt wise, however the flash /ignition point of gas is about 400C appropriately you infatuation a naked flare or spark to set it off and Ive used this method for many years without incident. function your showing off through each realizable joint one at a become old 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 allow a adopt blast of gas into each area, especially those hard to achieve considering large implements.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. in imitation of I unplug it and rule the motor, the car runs aggressive and at 850ish. I can unaccompanied guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much control in the swing of rpm though? I think it on your own 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 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 a part many factors may cause the similar symptom(s)
