    lol you opened the hood and someone swapped the LS1 for and LT1? lol those dumb asses did you a favor.
    Well if you just replaced the cap you forgot to change the rotor... or did you?... or did you swap the entire optispark unit?
    Other things to check are the coil and ICM, the opti plug, and check you spark plug wires and spark plugs. I have no clue on what the codes mean but check the basic crap first to make sure and by then I'm sure someone will pipe in on what the code means.
