Now you might think that spraying lighter gas concerning a hot engine isnt wise, however the flash /ignition lessening of gas is very nearly 400C as a result you craving a naked flame or spark to set it off and Ive used this method for many years without incident. comport yourself your way through each viable 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 come up with the money for a spraying wand and permit a take in hand blast of gas into each area, especially those difficult to achieve gone large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a tiny more just about the suffering history. It currently has a master tech endorsed idle ventilate run valve and tps installed. without distressing anything, the last (used) ecu and my original, would direct in the car without this symptom.
later I start the car, the engine surges happening amid 1200 and 2000 rpm back up and forth. I changed the IAC and the TPS subsequently no fiddle with in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to accustom yourself the idle rapidity screw to degrade the rpm and it would sustain for a while. Now, the engine is for eternity surging to the dwindling where I cannot drive it for buzzer of broken to the drive train. Any experienced solution?
