hey did you ever get the o2 sensor thing fixed. I have the same issue , it is the long tube headers it messes with the sensors. I so far have not got Bama tunes to get rid of it . The last tune they gave me killed my gas mileage ....wow. If you found a solution could you tell me about it. I have been trying to fix my engine light dilemma for 1 year nowI will try, theres 4 in my car, 3 of which are green :s.
I know the rear are blue but I had a mixture all over the place. Im going to get my mechanic to look over the harness, make sure the o2s are correctly placed as the previous o2 sensors were grinded on the connector to fit the location. :worshiphope this works, dying for a smog lol.
Thanks again Muckerpuck!
