Hey guys, bought this e30 m50 for next to nothing, figured I'd make it better and keep her for my pleasure. Swap was clearly done piss poorly, nothing worked when first got it. Slowly been babying her back to par. Now the problems I'm having are related to my air fuel ratio. I believe my car is running in "limp mode" due to jmproper hookups. My car stalls when I plug in maf, but runs decent without it. I've looked under the car at the o2 sensor as well, and to my surprise theres one actually sticking out of the pipe, however, there's about 6 inches of wire coming off, that isn't hooked to anything. The part that comes from the car is down there, just not hooked up, o2 sensor has four wires, and the wire coming from car has 4 wires. I'm so puzzled by this, any help would be greatly appreciated. Thanks
