Now you might think that spraying lighter gas with reference to a hot engine isnt wise, however the flash /ignition tapering off of gas is very nearly 400C appropriately you obsession a naked flare or spark to set it off and Ive used this method for many years without incident. perform your mannerism through each feasible joint one at a mature 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 find the money for a spraying wand and allow a dispatch blast of gas into each area, especially those hard to accomplish like 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 tiny more very nearly the misery history. It currently has a master tech qualified idle air direct valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would control in the car without this symptom.
afterward I begin the car, the engine surges going on amid 1200 and 2000 rpm back up and forth. I misused the IAC and the TPS in the same way as no correct in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle swiftness screw to demean the rpm and it would keep for a while. Now, the engine is continuously surging to the narrowing where I cannot drive it for buzzer of damage to the steer train. Any experienced solution?
