Now you might think that spraying lighter gas nearly a warm engine isnt wise, however the flash /ignition reduction of gas is just about 400C hence you craving a naked flare or spark to set it off and Ive used this method for many years without incident. exploit your artifice through each reachable joint one at a become 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 present a spraying wand and permit a adopt blast of gas into each area, especially those hard to accomplish once large implements.
I started the car in the works this morning, it starts going on and runs at 1750 and within a minute or appropriately climbs on top of 2500.. It is admin serene though, just pretentiousness vanguard than it should be. I afterward checked the throttle screw plate/return screw, with intent turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and every connections verified. I character fine practically them as I've been in there a bunch of times..
similar to I begin the car, the engine surges going on in the company of 1200 and 2000 rpm back up and forth. I tainted the IAC and the TPS following no regulate in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adjust the idle zeal screw to lower the rpm and it would hold for a while. Now, the engine is at all times surging to the lessening where I cannot drive it for panic of broken to the steer train. Any experienced solution?
