Normally the only time that fixes the problem is when the car will not run at all but is still getting fuel (aka the rotor shatters in the cap).
If you getting misfires and its not bad wires or plugs more than likely your Opti is on the way out and a new cap and rotor will not fix it.
I would give you a 20% chance thats your issue.

I believe in preventive maintenance...the contacts on an Opti's cap and rotor will burn and corrode just the same as any other conventional distributor's cap and rotor will.
I replaced my '96 Z-28's OE cap and rotor at 35,000 miles. The contacts weren't the greatest, although the car still ran reasonably well. Last summer, I changed the cap and rotor again, as the car had hit a little over 70,000 miles. However, I failed to notice that the rear bushing in the distributor's housing had developed a little play, and I heard a slight "clicking" noise when I had it all buttoned up and running again.
Bottom line, the play in the bushing was allowing the rotor to move around a bit, and it was hitting the inside of the cap. I wound up replacing the entire unit, and kept the "almost new" cap and rotor for the next 30,000 mile replacement....

My oem cap and rotor lasted 140k miles. New one has been on for 30k miles and still going strong. I see no need to change it.

I had a missing problem after I bought my car. I changed plugs and wires, that didnt solve it. I bought an MSD cap and coil and the car has ran perfectly since. Also i didnt see what year your car is but if its a non vented opti I would personaly upgrade to a vented opti spark.
