opti spark problem? will it hurt performance

i have a 1996 firebird that since ive had it hasn't run like it ran for the previous owner
the old owner ran low 13's with intake exhaust and 3.73's

now i have the car and i have intake exhaust 3.73's, 58mm intake manifold, 58mm throttle body, ecu, hyperground grounding kit, bbk shorty headers, electric cutout, throttle body bypass, intake silencer removed, Airfoil,
and i'm running 13.9-14.4

when the car is out in the rain and gets wet sometimes it won't start, and otherwise it is very had to start
it will spark and turn over but won't completely start up.

and once i do get the wet car started it is very sluggish and drives like ****.

i've been told that the problem is my opti spark.


could the opti spark be the reason the car isn't running anything like it had before?


im trying to get my car running in low 13's and 12's like it used to, would a dying opti spark be the cause of my speed decrease?



would my

Could be the opti, but I'd check the plug wires before diving in on the opti.

Is the SES on? If it is, and it is a good idea even if it isn't, is to have any trouble codes pulled.

SES = Service Engine Soon light or Check Engine light. It means the PCM has latched a code.
