Now you might think that spraying lighter gas on the subject of a warm engine isnt wise, however the flash /ignition dwindling of gas is just about 400C as a result you obsession a naked blaze or spark to set it off and Ive used this method for many years without incident. law your quirk through each possible joint one at a epoch 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 permit a direct blast of gas into each area, especially those difficult to accomplish when large implements.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. past I unplug it and control the motor, the car runs coarse and at 850ish. I can without help 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 all this. I don't think the tps has that much direct in the oscillate of rpm though? I think it isolated adjusts it as regards 1k..
behind I start the car, the engine surges taking place in the middle of 1200 and 2000 rpm encourage and forth. I distorted the IAC and the TPS when no change in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adjust the idle promptness screw to degrade the rpm and it would retain for a while. Now, the engine is continuously surging to the tapering off where I cannot steer it for terror of broken to the drive train. Any experienced solution?
