I agree with PhireX. The four step can be used to give you any number of steps once you learn it. It does sound like you have a timing issue. The stutter step might be because your arm is out of sync with your footwork. How are you at the line? Are you balanced there?
As MSC2471 said, the best thing would be to get a coach to watch you. Sometimes even doing something correct will 'feel' wrong because it is something new for the body's muscles and will not 'feel' correct until you get the muscle memory down. Having a coach to give you feedback on what you are doing and offering ideas of what to do correctly is of great benefit.
If you dont have a coach available in your area, check out some of the tips that are available on the web. One such site is:

Here is a picture of a bowler in the four step (cant find anything better right now):
