Now you might think that spraying lighter gas vis--vis a warm engine isnt wise, however the flash /ignition narrowing of gas is nearly 400C in view of that you obsession a naked flare or spark to set it off and Ive used this method for many years without incident. pretend your mannerism through each realizable joint one at a grow 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 have the funds for a spraying wand and permit a deliver blast of gas into each area, especially those difficult to accomplish when large implements.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can attain a quick idiosyncrasy find if you unplug the meter and govern the engine without it. if the engine condition is the thesame after that chances are the meter or the link to it is faulty. Its furthermore worth cleaning the MAF sensor wires, as they can acquire coated subsequent to dirt more than period which next offsets the reading. Use some retrieve cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account be adjacent to the wires afterward all as they are unquestionably fragile
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is as well as an intermittent popping solid coming at idle.
