Optispark replacment NO POWER now. IM STUCK IN LA
So my opti went out not to long ago and i just finished replacing the cap and rotor. It seems the rotor broke off the little tab that holds it in place so it was spining freely. I would get loud backfires and would not start. anyways i replaced it along with an accel ignition coil and it started right up, only problem is that it has no power at lower RPMs and it will backfire and then bog down but pick back up. It also sounds like i got a cam installed.
I feel as if the timing might have been thrown off as i did spin the crankshaft pully when trying to remove it. i finally got it off but did not know in what position it was on. i did not rotate the hub at all so i could not have thrown it off from there i think but i did not remember in which way i removed it. The balancer came off easily and when back on easily, it was only hard when trying to put it back in diffrently so i dont know if this was it.
Also possibly mabye i got the spark park wires on wrong. i doubled checked them but i still might have missed the psgr side since its so hard to see.
Any help is greatly appriciated as im currently stuck in LA and have school tommarow in San Fransisco. Thanks guys for the help.
i have a 94 LT1 Stock, BAD CATS.

im thinking plug wires becuase when i removed the old rotor it was broken(the little nipple that goes into the curcular disc) so there was only one way it could have been seated. ill go check the plugs guys. is there anything i could have missalligned with the balancer?
Thanks guys, life savers.

The backfiring is a timing issue, and because you changed the central nervous system of the ignition then that is your issue. Did you take the opti completely off when you changed the cap/rotor? If so, it would seem the splined shaft is not indexed correctly. And no, do not drive it like that until you find out what's going on.

Ok you guys ready for the long **** list of codes i got. Some are not related as i had SES on prior and i have an idea what was wrong but this is what i got in order.
14,37,45,44,43,42,55,54,53, & 51
14-Colent sensor or curcuit fualt-signal volts low or shorted
37-break switch on
45- rich exhuast indicated(left side on dual o2 models)
44-lean exhuast indicated (left side on o2 models)
43-ELECTRONIC SPARK TIMING (EST) CIRCUT- LOW VOLTS DETECTED 2. ELECTRONIC SPARK CONTROL CESC CIRCUIT PROBLEM
42-ELECTRONIC SPARK TIMING (EST) CIRCUT-OPEN OR SHORTED
53-ecm fualt or oxygen solenoid #3 falure (3.8L vin 1) or fuel lean monitor corvette.
54-fuel pump circuit fault or misture control (M/C) solenoid fualt or ECM fualt/EGR solenoid #2 falure (3.8L VIN 1)
53-System volts to high (OVER 17.7 VOLTS to ECM) or altanator volts not normal or vic anti theft fualt. This i know is to be fualty.
thats the boatload. I have no idea where to start the people at the auto shop wanted to charge me 180 for dinosgtics so i said **** that and bought my own scan tool for 200. Im way beyond speechlessi have no idea what to do. Any help is greatly appriciated, thanks.

sorry about that. no i just replaced the cap and rotor. So i dont se as how i could have installed it wrong, the little tab on the rotor only goes in one way. unless it fell off when i installed the cap on but i mad sure it stayed in place when i installed it.

i spent 200 on the cap and rotor so im broke now with all the other **** ive bought. Damit. I ordered the opti from autozone and told them the opti spark, when i got there it was just the cap and rotor and the guy said that how they come and that all i need. I should have listened to my instincts and not have taken the part out of desperation.
