Check each cylinder first by removing each plug wire while the engine is running. Each cylinder that is firing causes the engine rpm to drop when the spark plug wire is removed.A dead cylinder will maintain the same rpm when the wire is removed. If a cylinder is not firing, change the wire and/or plug,cap etc.If that does not correct the problem,run a compression test on the bad cylinder. Low compression could indicate a burnt valve.Check the valve lash, height of cam lobes.
