i have a 91 318, and i was getting the fault code 1222, and i guess that means the car is running lean or rich - well the oil smells like gas and and level has risen a little bit, so i'm guessing its running rich - anybody think they might konw whats wrong? i saw there was a separate code for the O2 sensor, but i didn't get that from the car. jsut taht it was running rich or lean - thanks, Luke
1222 Lambda Control 1
Thats a O2 sensor.

do u know a good way to check for sure? i have the chilton manual and it goes through some stuff using a volt meter, but it talks about some cars having a HO2/O2 sensor - i don't think my car has that, is taht only on newer ones?
