Could be a multitude of things. As suggested above check all coil packs for cracks in the rubber where the spark could be jumping out. Secondly check the gap on the plugs you are using as sometimes slightly lowering it could result in the misfire going away.

Another problem that is common is the air flow meter being stuffed resulting in the car running terrible/ misfiring due to over fueling etc.

The best thing you can do is pay the money to get someone who KNOWS what they are looking for to fix it in case it is damaging your engine. I'm sure if you tell us what city you are in someone can recommend a good workshop.
