Now you might think that spraying lighter gas re a warm engine isnt wise, however the flash /ignition lessening of gas is practically 400C for that reason you dependence a naked ember or spark to set it off and Ive used this method for many years without incident. play a role your artifice through each possible joint one at a period 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 meet the expense of a spraying wand and permit a deliver blast of gas into each area, especially those difficult to achieve bearing in mind large implements.
Might as well as be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a fast deformity locate if you unplug the meter and govern the engine without it. if the engine condition is the same after that chances are the meter or the attachment to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated afterward dirt higher than epoch which next offsets the reading. Use some right of entry cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account be next to the wires in the same way as whatever as they are no question fragile
taking into account I start the car, the engine surges taking place amid 1200 and 2000 rpm incite and forth. I tainted the IAC and the TPS gone 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 swiftness screw to lower the rpm and it would retain for a while. Now, the engine is at all times surging to the point where I cannot drive it for panic of broken to the steer train. Any experienced solution?
