Vehicle: Stock ass 1997 Civic EX with a D16Y8. ~160k miles

Problem: While accelerating, even at constant throttle, the car seems to bog/misfire randomly through the rpm range. It *seems* to be worse when the car is warmed but I'm not 100% sure. Sometimes when the car is warm it'll start really sluggishly, turns over a few times, then kinda sputters to life. It has set off a CEL for random misfire in cylinders 1 & 2 a total of three times in the past year while starting the car. Eventually, the car starts jerking so bad during acceleration that others in the car notice it and I wouldn't be surprised if people outside can tell. When this occurs I can replace the plugs and it will somewhat remedy the problem for a short time.

What I've Tried:
New dizzy
New dizzy cap/rotor
New plugs (correctly gapped)
New wires
New igntion coil
New fuel filter
Injector cleaner
Checked timing (was perfect, and yes I jumped the service connector and used a timing light)
Only run Chevron gas
Checked compression (got 180s across all cylinders, but I turned the engine over about 10 times before checking so maybe that messed up the readings)
Checked TPS with multimeter, seemed fine.

Like I said, the crap is completely random while I'm accelerating. It doesn't matter if I'm at WOT or partial throttle. Doesn't matter if the throttle is held constant or not. Seems to happen more when the engine is warm.

I am pretty darn close to having all the parts needed for the turbo setup, but I'd like to fix this problem before I throw it on. The car also has a problem with oil...it disappears. I don't have black smoke, so I don't think it's burning oil but maybe the cat is just catching it, I don't know. I think it's leaking from the rear main seal because there seems to be oil drip marks near the tranny, but it doesn't leak when parked.

Any suggestions would be great.
