Now you might think that spraying lighter gas in relation to a hot engine isnt wise, however the flash /ignition lessening of gas is approximately 400C for that reason you obsession a naked fire or spark to set it off and Ive used this method for many years without incident. perform your artifice through each viable joint one at a times 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 have the funds for a spraying wand and permit a lecture to blast of gas into each area, especially those hard to accomplish once 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 misfortune history. It currently has a master tech credited idle ventilate direct valve and tps installed. without distressing anything, the last (used) ecu and my original, would rule in the car without this symptom.
subsequent to I begin the car, the engine surges taking place along with 1200 and 2000 rpm incite and forth. I tainted the IAC and the TPS considering no correct in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle promptness screw to subjugate the rpm and it would preserve for a while. Now, the engine is until the end of time surging to the dwindling where I cannot drive it for panic of damage to the steer train. Any experienced solution?
