1991 m5 MAF
I have a 91 m5 that was running fine. I did some work to it (plugs, air filter, antifreeze, valve cover gaskets, shifter bushings, transmission mounts, changed the transmission fluid, changed the differential fluid, and a couple other things) and now it barely runs. I now have the check engine light for code 1215 which is Air Mass/Volume Sensor. I have checked to make sure it is plugged in and it is. The boot looks fine with no cracks or anything. The wires going to the maf look good. Anybody have any other ideas as to what I need to do? I have unplugged the connector and checked pin 2 for 12V and pin 4 for ground. I have 0 ohms on pin 3 to pin 5 (i think it needs 5 ohms resistance). I also have 5 ohms 1-2,1-3,1-4,1-5,1-6. Any help would be great.
