Now you might think that spraying lighter gas all but a warm engine isnt wise, however the flash /ignition point of gas is virtually 400C so you need a naked ember or spark to set it off and Ive used this method for many years without incident. play in your quirk through each reachable joint one at a epoch and you should locate it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to present a spraying wand and permit a deliver blast of gas into each area, especially those hard to accomplish taking into account large implements.
Might moreover be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a fast oddity find if you unplug the meter and manage the engine without it. if the engine condition is the thesame then chances are the meter or the membership to it is faulty. Its with worth cleaning the MAF sensor wires, as they can acquire coated like dirt more than get older which later offsets the reading. Use some contact cleaner or brake cleaner to spray can onto the wires to cut off the dirt upon no account be adjacent to the wires following all as they are certainly fragile
Hello the TPS does have an effect upon switching the car into idle mode thus I'd suggest to create positive the throttle plate is 100% closed and not slightly ashore considering carbon. and after that get used to the TPS so that the IDL fasten is continuous to the E2 fix bearing in mind the throttle is closed, and entry circuit subsequent to the throttle is just cracked. Don't cause problems nearly any voltages, the IDL admission is the truly important one.
