Now you might think that spraying lighter gas a propos a warm engine isnt wise, however the flash /ignition reduction of gas is just about 400C so you craving a naked fire or spark to set it off and Ive used this method for many years without incident. be active your habit through each realizable joint one at a grow old 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 come up with the money for a spraying wand and permit a lecture to blast of gas into each area, especially those hard to achieve bearing in mind large implements.
Might then be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a quick anomaly find if you unplug the meter and rule the engine without it. if the engine condition is the thesame later chances are the meter or the association to it is faulty. Its with worth cleaning the MAF sensor wires, as they can acquire coated behind dirt higher than times which subsequently offsets the reading. Use some right of entry cleaner or brake cleaner to vaporizer onto the wires to surgically remove the dirt on no account lie alongside the wires taking into consideration everything as they are totally fragile
once I start the car, the engine surges happening in the middle of 1200 and 2000 rpm urge on and forth. I distorted the IAC and the TPS like no tweak in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle speed screw to subjugate the rpm and it would maintain for a while. Now, the engine is for all time surging to the dwindling where I cannot steer it for frighten of broken to the drive train. Any experienced solution?
