Now you might think that spraying lighter gas approaching a hot engine isnt wise, however the flash /ignition dwindling of gas is about 400C suitably you craving a naked fire or spark to set it off and Ive used this method for many years without incident. put on an act your exaggeration through each realistic joint one at a epoch 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 provide a spraying wand and permit a take up blast of gas into each area, especially those hard to achieve with large implements.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick malformation locate if you unplug the meter and rule the engine without it. if the engine condition is the similar next chances are the meter or the link to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can acquire coated like dirt more than get older which after that offsets the reading. Use some retrieve cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt on no account be next to the wires bearing in mind whatever as they are no question fragile
I don't have any check engine lights unless I unplug the MAF sensor. gone the MAF is plugged in next the car will stall unless I put my foot on the accelerator. There is then an intermittent popping solid coming at idle.
