Is the check engine light on and if so are you getting any fault codes?

Do you have good spark at the misfiring cylinder as well as injector pulse?

Have you checked the engine compression?

Have you checked the compression on the #2 cylinder and compared it with one of the other good firing cylinders?

Will do.

If you are sure you have good spark as well as injector pulse with new injectors then that would be the next step, let me know the results.
