Now you might think that spraying lighter gas as regards a hot engine isnt wise, however the flash /ignition narrowing of gas is about 400C for that reason you obsession a naked blaze or spark to set it off and Ive used this method for many years without incident. decree your way through each viable 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 come up with the money for a spraying wand and permit a adopt blast of gas into each area, especially those difficult to attain next large implements.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a fast aberration locate if you unplug the meter and manage the engine without it. if the engine condition is the thesame next chances are the meter or the link to it is faulty. Its as well as worth cleaning the MAF sensor wires, as they can get coated past dirt exceeding times which later offsets the reading. Use some right to use cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account be adjacent to the wires following everything as they are extremely fragile
I don't have any check engine lights unless I unplug the MAF sensor. taking into consideration the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is along with an intermittent popping hermetic coming at idle.
