Had to read the post again. Ok, your rear 02`s are there to make sure you have properly working cats. If you dont have cats, mil`s or a tuner should correct the CEL. Your front 02`s are there for air/fuel mixture. Therefore you have another problem if the CEL keeps lighting up. What other mods have you done to your car?

 

Well it has, MSD Coil Packs, MSD 8.5 Wires, Upper T/b Spacer, Cold Air Intake, Underdrive Pulleys, Another T/b intake on the cold air side, Hypertech programming, H pipe, no cats, performance clutch and shifter, I am going to take it to a friend that owns a rebuild place this friday and have him hook it up to his snap on computer and read it and hopefully change it that way.
