The easiest thing to do is pull the plug and look at it. If the plug is jet black and not a shade of chocolate brown, it's running too rich. The other thing that has plagued people have been coil failures. That's easy enough to check. Simply swap coils with #3 and see what happens.

But depending on the intake it could be a rich issue.

The other (more drastic) thing it could be is a lack of compression in cylinder 1. While not typical, it's possible. A compression test is easy, quick, and will identify that problem.
