45-rich exhuast indicated (left side on dual o2 models)
44-Lean exhuast indicated (same as above)
43-electric spark timing (est) circut-low volts detected
42-electric spark timing (est) circut open or shorted
55-ECM fualt or oxygen solenoid #3 falure
54-fuel pump circuit fualt or mixture control (M/C) solenoid fualt or ECM fualt/EGR solenoid #2 falure V6 code i think
53-system voltage to high 17.7 volts to ECM or altnator volts not normal or vic anti theift fua;t
51-comp problem fualty wrong or incorrect PROM circuit or ECM PCM falure

I feel really stupid and abused by that ******* at autozone.. FML this just gets worse. So im gonna go by that new opti. if it dont work well i guess ill just live in a BOx. Thanks for your help.
Let us know how it turns out! He could just be ignorant about LT1 opti's/cap and rotors many people are (I used to be, but 17 years of LT1 ownership you WILL learn a thing or two about them LOL), I surely hope he didn't do that on purpose or he deserves a special place in hell

Verdad Gallardo Glad to hear you got a good opti from Autozone, (many on here don't). Looks like the "Duralast gold opti" is the one to get it's only $10 more....not the "Cardone" one they also sell, tons of threads about dead brand new Cardone optis. Just curious...does that Duralast gold opti box say where it's made?

I have read multiple stories about phantom codes with the Innova brand. Avoid, if possible is all I can say.
