CEL for O2, help
Hey, I just bought a 2000 6spd from a fellow forum member. The engine mods are professionally tuned Magnuson supercharger, LG long tube full exhaust with x-pipe, cats and Big3 4-tip muffler.
I am getting a CEL with the following codes: P0134, P0154, P1133 and P1153. I understand that those are for the front O2 sensors. Both are present, as are the rears. What should I be looking for as a potential cause?

Congrats on your new Vette.
You have some pretty series mods so my guess is that your current tune (either stock or modified) is having a hard time with your current set up. Since the codes are all O2 related you have a mis read with your down stream. The codes are either no detection or no reading. The simple thing is to replace the O2 sensors. If that does not work you may have to retune the engine.
