Now you might think that spraying lighter gas a propos a hot engine isnt wise, however the flash /ignition tapering off of gas is approximately 400C in view of that you craving a naked ember or spark to set it off and Ive used this method for many years without incident. behave your mannerism through each doable joint one at a period 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 pay for a spraying wand and permit a attend to blast of gas into each area, especially those hard to attain subsequent to large implements.
Might then be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a quick aberration locate if you unplug the meter and direct the engine without it. if the engine condition is the similar after that chances are the meter or the attachment to it is faulty. Its next worth cleaning the MAF sensor wires, as they can get coated considering dirt beyond mature which subsequently offsets the reading. Use some retrieve cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account touch the wires as soon as all as they are very fragile
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is as a consequence an intermittent popping unquestionable coming at idle.
