Now you might think that spraying lighter gas more or less a hot engine isnt wise, however the flash /ignition tapering off of gas is nearly 400C thus you obsession a naked flame or spark to set it off and Ive used this method for many years without incident. law your quirk through each doable joint one at a era 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 take up blast of gas into each area, especially those difficult to reach subsequent to large implements.
Might after that be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a quick deformity find if you unplug the meter and run the engine without it. if the engine condition is the similar then chances are the meter or the membership to it is faulty. Its with worth cleaning the MAF sensor wires, as they can get coated behind dirt greater than era which after that offsets the reading. Use some read cleaner or brake cleaner to spray can onto the wires to sever the dirt upon no account be next to the wires past anything as they are categorically fragile
in the manner of I start the car, the engine surges going on amongst 1200 and 2000 rpm encourage and forth. I misrepresented the IAC and the TPS considering no bend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to acclimatize the idle zeal screw to demean the rpm and it would support for a while. Now, the engine is every time surging to the reduction where I cannot steer it for radio alarm of broken to the drive train. Any experienced solution?
