Now you might think that spraying lighter gas vis--vis a warm engine isnt wise, however the flash /ignition narrowing of gas is just about 400C correspondingly you obsession a naked flare or spark to set it off and Ive used this method for many years without incident. conduct yourself your way 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 present a spraying wand and permit a forward blast of gas into each area, especially those hard to reach behind large implements.
Might moreover be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a quick defect locate if you unplug the meter and control the engine without it. if the engine condition is the same subsequently chances are the meter or the link to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated taking into consideration dirt more than period which next offsets the reading. Use some approach cleaner or brake cleaner to spray can onto the wires to separate the dirt upon no account be next to the wires bearing in mind everything as they are completely fragile
I don't have any check engine lights unless I unplug the MAF sensor. behind the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is as well as an intermittent popping sound coming at idle.
