Now you might think that spraying lighter gas approximately a hot engine isnt wise, however the flash /ignition dwindling of gas is not quite 400C consequently you craving a naked fire or spark to set it off and Ive used this method for many years without incident. play-act your exaggeration through each possible joint one at a period and you should find it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to offer a spraying wand and permit a speak to blast of gas into each area, especially those difficult to attain in the same way as large implements.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a fast deformity locate if you unplug the meter and run the engine without it. if the engine condition is the similar later chances are the meter or the membership to it is faulty. Its along with worth cleaning the MAF sensor wires, as they can get coated past dirt beyond period which subsequently offsets the reading. Use some retrieve cleaner or brake cleaner to spray can onto the wires to remove the dirt on no account be adjacent to the wires behind all as they are totally fragile
in the manner of I start the car, the engine surges up amongst 1200 and 2000 rpm back up and forth. I misrepresented the IAC and the TPS subsequently no fine-tune in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to become accustomed the idle rapidity screw to belittle the rpm and it would withhold for a while. Now, the engine is forever surging to the tapering off where I cannot steer it for startle of damage to the drive train. Any experienced solution?
