Im getting many codes and my car runs crappy, not shaky but it feels like im driving a 4 cyl car. once i reach higher RPMs it will hook but only momentarily bc soon after ill get a misfire and it will bog down. it will also shut off periodically, im so stumped i need help if anyone with the same prob can help me out i would greatly appriciate it.

I changed the cap n rotor only along with ignition coil. Hear are the codes.

45,44,43,42,55,54,53,51

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

any help wpuld be appriciated. i have another post for this but im getting really desprate due to my issue, im stuck in LA and i just want to fix it so i can go home
thanks for the help.

 

Put a new AC delco opti on it, (not just a cap and rotor).

 

so its the opti thats bad?

 

More than likely.....see my rant in other thread about your autozone moron!!!!

 

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.

 

Best of luck! 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

 

Thanks man, ill do the install tommarow and let you know how it turns out. thanks again. take care.

 

it was the opti. all fixed thanks a million guys, you saved my life. lol. Thanks once again.

Its still thowing the same codes but i have no SES no more. wierd maybe my reader sucks. its an innova 2130d i think. heard they have problems reading this 94 lt1 model.

 

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 dont really know about the made in the usa part but it only has a 90 day warrenty. the cardone one has a lifetime one.

 

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

 

Hey, if it works, it works...opti's for life would not be such a bad deal if the labor involved was not such a PITA!
