Lots of possibilities = lots of questions.

Did it always run this way?

Or did it start after you made a change? i.e.cap and rotor

What steps have you taken already?

You will need to start ruling things out. The engine needs the right combination of gas, spark and air. Chances are only one of those is messed up. Narrow it down to one of those three and you will be a lot closer to identifying the problem.
