which cylinder/cylinders? If its just one then its most likely just the spark plug/wires. If its two then probably coil packs. Also could be a fuel issue as well

Check your valves. Sometimes what you think is a misfire is a bad valve or bad valve adjustment.

Your car may not be getting enough air. Make sure that you're intake system is running right. You might also check your radiator and the coolant fluid.
