Now you might think that spraying lighter gas approximately a hot engine isnt wise, however the flash /ignition tapering off of gas is just about 400C hence you obsession a naked flame or spark to set it off and Ive used this method for many years without incident. accomplish your exaggeration through each practicable joint one at a era and you should locate 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 allow a focus on blast of gas into each area, especially those difficult to attain considering large implements.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick malformation find if you unplug the meter and govern 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 with worth cleaning the MAF sensor wires, as they can get coated taking into consideration dirt exceeding get older which then offsets the reading. Use some admittance cleaner or brake cleaner to spray can onto the wires to surgically remove the dirt upon no account be adjacent to the wires considering everything as they are enormously fragile
I don't have any check engine lights unless I unplug the MAF sensor. in the manner of the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is as a consequence an intermittent popping strong coming at idle.
