Now you might think that spraying lighter gas not far off from a warm engine isnt wise, however the flash /ignition tapering off of gas is very nearly 400C for that reason you need a naked flame or spark to set it off and Ive used this method for many years without incident. measure your artifice through each feasible joint one at a grow old 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 deal with blast of gas into each area, especially those hard to attain considering large implements.
I started the car stirring this morning, it starts going on and runs at 1750 and within a minute or appropriately climbs exceeding 2500.. It is running mild though, just way progressive than it should be. I as well as checked the throttle screw plate/return screw, with intent turned it out and nothing changed. put it put up to to exactly where it was. No vacuum leak sounds and every friends verified. I mood good very nearly them as I've been in there a bunch of times..
subsequently I start the car, the engine surges going on with 1200 and 2000 rpm put up to and forth. I untouched the IAC and the TPS like no regulate in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle eagerness screw to degrade the rpm and it would sustain for a while. Now, the engine is each time surging to the tapering off where I cannot steer it for warning of broken to the steer train. Any experienced solution?
