Now you might think that spraying lighter gas re a warm engine isnt wise, however the flash /ignition dwindling of gas is virtually 400C as a result you craving a naked ember or spark to set it off and Ive used this method for many years without incident. take action your exaggeration through each practicable joint one at a period 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 give a spraying wand and permit a deal with blast of gas into each area, especially those hard to reach subsequently large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a little more just about the difficulty history. It currently has a master tech approved idle ventilate manage valve and tps installed. without touching anything, the last (used) ecu and my original, would manage in the car without this symptom.
bearing in mind I start the car, the engine surges happening surrounded by 1200 and 2000 rpm put up to and forth. I misrepresented the IAC and the TPS past no amend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle readiness screw to subjugate the rpm and it would withhold for a while. Now, the engine is for all time surging to the narrowing where I cannot drive it for panic of broken to the steer train. Any experienced solution?
