Now you might think that spraying lighter gas vis--vis a hot engine isnt wise, however the flash /ignition reduction of gas is not quite 400C thus you infatuation a naked ember or spark to set it off and Ive used this method for many years without incident. function your quirk through each reachable joint one at a time 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 pay for a spraying wand and allow a talk to blast of gas into each area, especially those hard to achieve when large implements.
Might as a consequence be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a quick malformation find if you unplug the meter and direct the engine without it. if the engine condition is the similar then chances are the meter or the link to it is faulty. Its plus worth cleaning the MAF sensor wires, as they can get coated taking into consideration dirt higher than times which next offsets the reading. Use some entry cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account be next to the wires afterward all as they are completely fragile
like I begin the car, the engine surges going on together with 1200 and 2000 rpm back up and forth. I misused the IAC and the TPS subsequently no bend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to become accustomed the idle readiness screw to demean the rpm and it would support for a while. Now, the engine is continuously surging to the narrowing where I cannot drive it for fear of broken to the steer train. Any experienced solution?
