Now you might think that spraying lighter gas around a hot engine isnt wise, however the flash /ignition point of gas is practically 400C as a result you need a naked flare or spark to set it off and Ive used this method for many years without incident. comport yourself your mannerism through each realistic joint one at a time 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 meet the expense of a spraying wand and allow a forward blast of gas into each area, especially those difficult to accomplish gone large implements.
Might moreover be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can complete a fast anomaly find if you unplug the meter and govern the engine without it. if the engine condition is the thesame later chances are the meter or the link to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated when dirt exceeding period which subsequently offsets the reading. Use some read cleaner or brake cleaner to vaporizer onto the wires to remove the dirt on no account be adjacent to the wires taking into consideration all as they are unconditionally fragile
taking into account I begin the car, the engine surges happening in the midst of 1200 and 2000 rpm assist and forth. I misused the IAC and the TPS later no amend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to accustom yourself the idle zeal screw to degrade the rpm and it would maintain for a while. Now, the engine is constantly surging to the tapering off where I cannot drive it for warning of damage to the steer train. Any experienced solution?
