ok so here is the short story I pulled the tranny to change my clutch/flywheel and when I put the it back in the bank 1 sensor 1 02 is bad(the one in the header b4 the cat). I was up at ballistic this weekend and scott and giles had a thought of a bad ground that i didn't put back on. which makes sense to me. I was just wondering if there was any other ideas for me to check this week before I go back to get it tuned. I have put a new sensor in so I know it shouldn't be that plus it worked fine before i pulled the tranny.
