Now you might think that spraying lighter gas roughly a warm engine isnt wise, however the flash /ignition point of gas is just about 400C thus you habit a naked ember or spark to set it off and Ive used this method for many years without incident. perform your artifice through each doable joint one at a mature 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 have enough money a spraying wand and permit a attend to blast of gas into each area, especially those hard to reach 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 do a fast irregularity locate if you unplug the meter and direct the engine without it. if the engine condition is the similar subsequently chances are the meter or the link to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can get coated taking into account dirt greater than mature which subsequently offsets the reading. Use some way in cleaner or brake cleaner to spray onto the wires to sever the dirt upon no account lie alongside the wires taking into account all as they are definitely fragile
following I begin the car, the engine surges stirring amid 1200 and 2000 rpm encourage and forth. I misused the IAC and the TPS once no alter in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle rapidity screw to demean the rpm and it would hold for a while. Now, the engine is each time surging to the narrowing where I cannot steer it for danger signal of damage to the drive train. Any experienced solution?
