Bought a 1987 325is about two weeks ago. One of the most important things that needs fixing is the O2 sensor, and I just bought a new one only to discover that it isn't going to work.
The PO must've changed out the connector with something universal. Can't figure out what it is or what kind it is. Anybody know if I can get a new connector from a BMW dealership or anywhere online? My CEL comes on after my engine is good and warmed up, Motronic gives me a 2-flash O2 sensor indicator.
