My 91 does the exact same thing. It runs amazing when cold, horrible when at running temp. I have replaced plugs, wires, fuel filter, cleaned O2 sensor relaced knock sensors, and replaced exhaust with 3inch catless so i couldn't have clogged cats. i am completely stumped, more information would be great.
