What is a optispark, what does it do, and where is it on 1994 Pontiac Firebird

My firebird has a miss, but only in the lower rpm's. Replaced plugs and wires still has the miss. That's why I'm asking about a optispark. Thinks for any help you can give me.

Opti-spark is the type of distributor the ignition system has. They have a lot of problems with the distributor itself. I recommend you take it to a repair shop for proper diagnosis unless you want to continue and throw parts at it.
