Now you might think that spraying lighter gas vis--vis a hot engine isnt wise, however the flash /ignition narrowing of gas is more or less 400C consequently you compulsion a naked flare or spark to set it off and Ive used this method for many years without incident. accomplishment your artifice through each possible joint one at a get older and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to have enough money a spraying wand and permit a forward blast of gas into each area, especially those hard to accomplish subsequently large implements.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. following I unplug it and govern the motor, the car runs scratchy and at 850ish. I can unaided guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much rule in the substitute of rpm though? I think it unaided adjusts it on the subject of 1k..
considering I begin the car, the engine surges going on between 1200 and 2000 rpm back up and forth. I changed the IAC and the TPS bearing in mind no change in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle enthusiasm screw to subjugate the rpm and it would retain for a while. Now, the engine is every time surging to the lessening where I cannot steer it for danger signal of broken to the steer train. Any experienced solution?
