SKIP the MSD idea. OE only! problem is VERY scarse to find! 1st simple diagnostics eliminating other possibilities. Codes, Fuel pressure, pump voltage, control module, Coil, plugs, wires?
A typical Opti going bad runs ok cold. Warms up. Then major misfires. But do not be the parts changer! Confirm!
