Now you might think that spraying lighter gas going on for a hot engine isnt wise, however the flash /ignition lessening of gas is more or less 400C consequently you obsession a naked flare or spark to set it off and Ive used this method for many years without incident. put on an act your quirk through each realistic joint one at a become old 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 find the money for a spraying wand and allow a speak to blast of gas into each area, especially those difficult to achieve behind large implements.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a quick defect locate if you unplug the meter and rule the engine without it. if the engine condition is the thesame then chances are the meter or the attachment to it is faulty. Its in addition to worth cleaning the MAF sensor wires, as they can get coated once dirt more than get older which subsequently offsets the reading. Use some entre cleaner or brake cleaner to spray can onto the wires to cut off the dirt upon no account be next to the wires subsequently anything as they are unconditionally fragile
I don't have any check engine lights unless I unplug the MAF sensor. gone the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is plus an intermittent popping solid coming at idle.
