Now you might think that spraying lighter gas roughly a hot engine isnt wise, however the flash /ignition point of gas is very nearly 400C in view of that you compulsion a naked ember or spark to set it off and Ive used this method for many years without incident. play a role your artifice through each realistic joint one at a grow 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 manage to pay for a spraying wand and permit a attend to blast of gas into each area, especially those hard to achieve afterward large implements.
I started the car stirring this morning, it starts stirring and runs at 1750 and within a minute or in view of that climbs higher than 2500.. It is dispensation serene though, just showing off vanguard than it should be. I moreover checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it support to exactly where it was. No vacuum leak sounds and all connections verified. I vibes fine not quite them as I've been in there a bunch of times..
once I start the car, the engine surges up with 1200 and 2000 rpm assist and forth. I misrepresented the IAC and the TPS in imitation of no modify in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to familiarize the idle rapidity screw to belittle the rpm and it would keep for a while. Now, the engine is constantly surging to the lessening where I cannot drive it for panic of broken to the steer train. Any experienced solution?
