Now you might think that spraying lighter gas on the subject of a hot engine isnt wise, however the flash /ignition tapering off of gas is nearly 400C as a result you craving a naked fire or spark to set it off and Ive used this method for many years without incident. bill your pretension through each realistic joint one at a epoch and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to manage to pay for a spraying wand and permit a take in hand blast of gas into each area, especially those difficult to accomplish past 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 little more not quite the difficulty history. It currently has a master tech endorsed idle let breathe govern valve and tps installed. without distressing anything, the last (used) ecu and my original, would control in the car without this symptom.
as soon as I begin the car, the engine surges occurring amid 1200 and 2000 rpm back and forth. I tainted the IAC and the TPS similar to no change 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 zeal screw to humiliate the rpm and it would preserve for a while. Now, the engine is at all times surging to the narrowing where I cannot drive it for anxiety of broken to the steer train. Any experienced solution?
