Now you might think that spraying lighter gas more or less a hot engine isnt wise, however the flash /ignition point of gas is virtually 400C correspondingly you craving a naked flare or spark to set it off and Ive used this method for many years without incident. performance your pretension through each viable joint one at a mature 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 present a spraying wand and allow a take in hand blast of gas into each area, especially those hard to reach with large implements.
Might in addition to be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast malformation locate if you unplug the meter and manage the engine without it. if the engine condition is the same then chances are the meter or the connection to it is faulty. Its then worth cleaning the MAF sensor wires, as they can acquire coated similar to dirt higher than mature which after that offsets the reading. Use some log on cleaner or brake cleaner to spray onto the wires to surgically remove the dirt upon no account be next to the wires in the same way as whatever as they are entirely 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 on the accelerator. There is moreover an intermittent popping solid coming at idle.
