Now you might think that spraying lighter gas around a hot engine isnt wise, however the flash /ignition lessening of gas is just about 400C in view of that you craving a naked flare or spark to set it off and Ive used this method for many years without incident. play-act your way through each attainable joint one at a times and you should locate it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to present a spraying wand and allow a refer blast of gas into each area, especially those hard to reach as soon as large implements.
I started the car taking place this morning, it starts taking place and runs at 1750 and within a minute or therefore climbs more than 2500.. It is dispensation mild though, just pretension innovative than it should be. I plus 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 contacts verified. I character good just about them as I've been in there a bunch of times..
later I start the car, the engine surges up along with 1200 and 2000 rpm urge on and forth. I untouched the IAC and the TPS subsequent to no tweak in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle quickness screw to subjugate the rpm and it would keep for a while. Now, the engine is continually surging to the narrowing where I cannot steer it for distress of broken to the steer train. Any experienced solution?
