Now you might think that spraying lighter gas not far off from a warm engine isnt wise, however the flash /ignition lessening of gas is virtually 400C for that reason you craving a naked ember or spark to set it off and Ive used this method for many years without incident. feat your habit through each realizable joint one at a become old and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to manage to pay for a spraying wand and allow a concentrate on blast of gas into each area, especially those difficult to attain with large implements.
Might next be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast defect find if you unplug the meter and control the engine without it. if the engine condition is the similar after that chances are the meter or the association to it is faulty. Its as a consequence worth cleaning the MAF sensor wires, as they can get coated following dirt over mature which after that offsets the reading. Use some log on cleaner or brake cleaner to vaporizer onto the wires to separate the dirt on no account adjoin the wires subsequent to anything as they are unquestionably fragile
bearing in mind I begin the car, the engine surges happening with 1200 and 2000 rpm back up and forth. I changed the IAC and the TPS later than no bend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to acclimatize the idle readiness screw to demean the rpm and it would preserve for a while. Now, the engine is each time surging to the tapering off where I cannot drive it for terror of broken to the drive train. Any experienced solution?
