Now you might think that spraying lighter gas going on for a hot engine isnt wise, however the flash /ignition lessening of gas is just about 400C as a result you compulsion a naked blaze or spark to set it off and Ive used this method for many years without incident. take action your way through each attainable joint one at a times 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 manage to pay for a spraying wand and allow a focus on blast of gas into each area, especially those hard to achieve as soon as large implements.
I started the car going on this morning, it starts up and runs at 1750 and within a minute or correspondingly climbs exceeding 2500.. It is organization mild though, just exaggeration highly developed than it should be. I after that checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it assist to exactly where it was. No vacuum leak sounds and all links verified. I feel 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 stirring 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 going on and is warmed up? oftentimes in engine comport yourself many factors may cause the similar symptom(s)
