I'm fed up with this!
Alright, this car is running so bad and I've tested fuel pressure, replaced the ICM, cap and rotor, coil, fuel filter, and plug wires. The damn car won't throw any codes, it stumbles under high load especially in the low rpms, it barely idles, constantly misfires, and it gets even worse when it warms up.
Someone please help, what the fick is wrong with my car?

I don't know what the plugs are gapped at but they have been in there awhile and I don't recall having this problem before. Perhaps it is a cracked plug but I have touched them recently so I"m not sure how they would become cracked. I'll take a look at the plugs tomorrow.

It's probably the optical sensor itself of the opti which took a ****....not the cap and rotor. Have the PCM scanned..there may not be an engine light or even a code stored unfortunately. From my experience, it's best to replace the whole damn thing while your down there unless you are just doing general preventive maintenance on a properly functioning opti. Unfortunately, your 93 car has the old un-vented opti like my car which is known to give more issues than later vented versions due to moisture buildup. (How old is your opti?) I got a very lightly used MSD opti (which is vented) that has performed flawlessly and cured a constant 5200 rpm miss caused by the old opti; something to consider since you probably have to dump some $$ on a good opti.
