Now you might think that spraying lighter gas around a hot engine isnt wise, however the flash /ignition point of gas is not quite 400C correspondingly you need a naked fire or spark to set it off and Ive used this method for many years without incident. be in your habit through each realizable joint one at a era 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 take in hand blast of gas into each area, especially those hard to attain subsequent to large implements.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. gone I unplug it and run the motor, the car runs rough and at 850ish. I can abandoned guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much run in the swap of rpm though? I think it unaided adjusts it going on for 1k..
subsequent to I start the car, the engine surges in the works amid 1200 and 2000 rpm back and forth. I changed the IAC and the TPS following no amend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to become accustomed the idle eagerness screw to demean the rpm and it would retain for a while. Now, the engine is for all time surging to the dwindling where I cannot drive it for panic of damage to the drive train. Any experienced solution?
