Now you might think that spraying lighter gas in relation to a warm engine isnt wise, however the flash /ignition point of gas is just about 400C suitably you dependence a naked ember or spark to set it off and Ive used this method for many years without incident. measure your exaggeration through each reachable joint one at a grow old 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 pay for a spraying wand and permit a attend to blast of gas into each area, especially those difficult to accomplish gone large implements.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. bearing in mind I unplug it and govern the motor, the car runs brusque and at 850ish. I can only guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much manage in the interchange of rpm though? I think it on your own adjusts it around 1k..
gone I begin the car, the engine surges in the works amongst 1200 and 2000 rpm back and forth. I misused the IAC and the TPS later than no fiddle with in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle quickness screw to demean the rpm and it would hold for a while. Now, the engine is at all times surging to the narrowing where I cannot drive it for agitation of damage to the steer train. Any experienced solution?
