well i went to town early this morning and the truck was running like shit...felt like it was on 5 or 6 cylindersi got it home with no ses light...let it cool off and started looking for a problem.....my lil black lab puppy decided to go lay under the truck and oh look what i found to chew up.....my 3' of extra o2 line on the 02 vette o2's.....took it off and cut all the fucked up wire off and reinstalled it.....the truck runs fine again....no codes...i left all that xtra wire on there because everyone was saying that it was setup to work with that much wire...well it looks like it will work just fine no matter what the length of the wire is.....the pooch got a wire whoopin too...dont think she will get into some wires again anytime soon....
