Now you might think that spraying lighter gas in the region of a hot engine isnt wise, however the flash /ignition point of gas is practically 400C appropriately you compulsion a naked flare or spark to set it off and Ive used this method for many years without incident. show your showing off through each reachable joint one at a epoch 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 present a spraying wand and allow a lecture to blast of gas into each area, especially those difficult to attain bearing in mind large implements.
Might with be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast irregularity find if you unplug the meter and direct the engine without it. if the engine condition is the thesame after that chances are the meter or the connection to it is faulty. Its then worth cleaning the MAF sensor wires, as they can acquire coated next dirt exceeding get older which later offsets the reading. Use some retrieve cleaner or brake cleaner to vaporizer onto the wires to sever the dirt on no account be next to the wires taking into consideration anything as they are utterly fragile
I don't have any check engine lights unless I unplug the MAF sensor. next the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping sound coming at idle.
