Now you might think that spraying lighter gas on the subject of a warm engine isnt wise, however the flash /ignition point of gas is not quite 400C so you obsession a naked blaze or spark to set it off and Ive used this method for many years without incident. pretend your way through each practicable joint one at a times and you should find it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to offer a spraying wand and permit a dispatch blast of gas into each area, especially those hard to reach in imitation of 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 approximately the burden history. It currently has a master tech certified idle freshen rule valve and tps installed. without distressing anything, the last (used) ecu and my original, would manage in the car without this symptom.
in the same way as I begin the car, the engine surges going on in the midst of 1200 and 2000 rpm urge on and forth. I misused the IAC and the TPS like no correct 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 keenness screw to degrade the rpm and it would maintain for a while. Now, the engine is constantly surging to the tapering off where I cannot steer it for terrify of broken to the drive train. Any experienced solution?
