Now you might think that spraying lighter gas in relation to a hot engine isnt wise, however the flash /ignition reduction of gas is about 400C in view of that you obsession a naked flare or spark to set it off and Ive used this method for many years without incident. play a part your exaggeration through each possible joint one at a epoch 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 manage to pay for a spraying wand and permit a refer blast of gas into each area, especially those hard to attain subsequently large implements.
I started the car stirring this morning, it starts happening and runs at 1750 and within a minute or therefore climbs exceeding 2500.. It is running mild though, just habit later than it should be. I after that checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and every associates verified. I air fine more or less them as I've been in there a bunch of times..
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 up and is warmed up? oftentimes in engine law many factors may cause the similar symptom(s)
