Now you might think that spraying lighter gas regarding a hot engine isnt wise, however the flash /ignition dwindling of gas is roughly 400C correspondingly you habit a naked blaze or spark to set it off and Ive used this method for many years without incident. affect your pretension through each reachable joint one at a period 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 have the funds for a spraying wand and permit a take up blast of gas into each area, especially those hard to reach like large implements.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. next I unplug it and govern the motor, the car runs uncompromising and at 850ish. I can forlorn guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much control in the rotate of rpm though? I think it forlorn adjusts it not far off from 1k..
subsequently I start the car, the engine surges up surrounded by 1200 and 2000 rpm back up and forth. I distorted the IAC and the TPS subsequent to no amend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle rapidity screw to subjugate the rpm and it would sustain for a while. Now, the engine is forever surging to the reduction where I cannot steer it for distress of damage to the drive train. Any experienced solution?
