decided to test the resistance of my afm today. My knowledge on car electronics and how to use a multimeter is limited. but i gave it ago and this was my result, can someone with better knowledge of multimeters and afm resistance please clarify what i have done is correct.
flick it to volts and you can test the mixture by putting the probes on wire 1 and 3 (1 is closest to your airbox) with the key on acc and measure the volts
3.6V is the factory setting and is a lean mix
2.0V being rich.
