like 11ventybillion different things dude.

start with a tune up (plugs/wires/cap/rotor)

also check your maf, make sure its not just slightly unplugged.

the single cam's about to spontaneously com bust. lol

However what your describing sounds like what Martin fixed on my single cam coupe like 5 years ago. It ended up being the TPS sensor.

Try doing a tune up and let us know what happened
