Now you might think that spraying lighter gas in relation to a hot engine isnt wise, however the flash /ignition point of gas is more or less 400C consequently you craving a naked fire or spark to set it off and Ive used this method for many years without incident. pretense your way through each doable joint one at a time 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 have the funds for a spraying wand and permit a direct blast of gas into each area, especially those hard to reach taking into consideration large implements.
Might as a consequence be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick deviation locate if you unplug the meter and manage 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 furthermore worth cleaning the MAF sensor wires, as they can get coated in the manner of dirt over become old which after that offsets the reading. Use some gain access to cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt on no account be next to the wires behind everything as they are totally fragile
I don't have any check engine lights unless I unplug the MAF sensor. subsequent to 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 solid coming at idle.
