Greetings,

I replaced the pre-cat sensor yesterday (first wrenching job on the car) with the Bosch premium oxygen sensor. after clearing all codes, drove for a bit (an hour or so) and the check engine light came on again. I read the codes and here are the results for my 2003 330XI 6 SPD:

Table 19 (Peake Tool)
CA - 02 sensor control limit cyl #1-3
C6 - catalytic converter efficiency cyl #1-3
E4 - 02 sensor adaptation limit cyl #4-6
E1 - aftercat fuel trim system cyl #1-3
EE - Misfire Cyl #1
FO - Misfire Cyl #3
EF - Misfire Cyl #2

I dunno what to do from here. Please advise and thank you so much.
