What's up Chido. I know this is old, but I'm at a dead end and wondered if you could shed some light on this issue. I know it's old, but it involves the repin method for going from ULEV to Non-ULEV. I did a 5 spd swap and have the ecm from a 99 Non-ulev in my 00 ULEV. I followed your directions for repinning, swapping O2 sensor, and jumping wires/remove relay, but still reading a code 1(primary O2 sensor). Do you have any more info and/or pics to help me out? I cant find any more info on how to fix this and hope u can help. Thanks,it's really appreciated!
