We swapped a LSV into a GSR and the car is throughing a Code 1 (o2) right off the bat, before even starting the car. Does anyone have any idea what that could be, the car never through O2 before we did the swap and we didnt even touch the harness, we built the motor and used the original harness and now there is a o2 code. SOMEBODY HELP MEE!!!! its pissing me off... let me know if anyone had this problem before and what they did to get rid of it. Thanks...
