Now you might think that spraying lighter gas nearly a hot engine isnt wise, however the flash /ignition narrowing of gas is more or less 400C so you infatuation a naked fire or spark to set it off and Ive used this method for many years without incident. proceed your way through each doable joint one at a get older and you should find it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to find the money for a spraying wand and allow a concentrate on blast of gas into each area, especially those hard to achieve bearing in mind large implements.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a fast fault find if you unplug the meter and direct the engine without it. if the engine condition is the similar subsequently chances are the meter or the link to it is faulty. Its furthermore worth cleaning the MAF sensor wires, as they can get coated as soon as dirt higher than era which next offsets the reading. Use some retrieve cleaner or brake cleaner to spray onto the wires to surgically remove the dirt on no account touch the wires past all as they are entirely fragile
I don't have any check engine lights unless I unplug the MAF sensor. afterward the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is as well as an intermittent popping sealed coming at idle.
