Now you might think that spraying lighter gas in relation to a warm engine isnt wise, however the flash /ignition point of gas is virtually 400C fittingly you need a naked ember or spark to set it off and Ive used this method for many years without incident. work your pretension through each realizable 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 give a spraying wand and permit a talk to blast of gas into each area, especially those hard to attain considering large implements.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. behind I unplug it and control the motor, the car runs scratchy and at 850ish. I can on your own guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much manage in the alternating of rpm though? I think it forlorn adjusts it roughly 1k..
in the manner of I start the car, the engine surges stirring amongst 1200 and 2000 rpm support and forth. I changed the IAC and the TPS with no change in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adjust the idle keenness screw to humiliate the rpm and it would sustain for a while. Now, the engine is each time surging to the point where I cannot steer it for agitation of broken to the drive train. Any experienced solution?
