Hi everyone. I just finnished replacing k03's on my 2000 s4 and the car drove fine, but it had check engine light on and didn't seem to pull like it should for a stg2. Finnally checked codes today and got 0741 and 1432. Secondary air injection system fault, and torque converter stuck on or open. The trans. Has been crazilly shifting a couple times and the car starts hard maybe everother time. Can someone please give a link or more information to/on 2ndary air injection system and torque converter fixes? Also is there any way to troubleshoot the TC code in order to narrow it down to the TC needing to be replaced before i pull the motor again?Thanks
