Now you might think that spraying lighter gas re a hot engine isnt wise, however the flash /ignition reduction of gas is not quite 400C therefore you dependence a naked flare or spark to set it off and Ive used this method for many years without incident. play your pretentiousness through each realizable joint one at a time 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 present a spraying wand and allow a deal with blast of gas into each area, especially those difficult to attain similar to large implements.
Its afterward worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will all repercussion in insufficient fuel subconscious delivered to the engine. Might as well as be worth cleaning out the idle eagerness manage motor / valve as these get clogged up once carbon and some brake cleaner washed through helps release things off.
in the same way as I begin the car, the engine surges stirring amongst 1200 and 2000 rpm incite and forth. I misrepresented the IAC and the TPS once no amend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to accustom yourself the idle speed screw to demean the rpm and it would withhold for a while. Now, the engine is all the time surging to the point where I cannot drive it for panic of broken to the steer train. Any experienced solution?
