CYLINDER MISFIRE - Experts help, please

The scanner indicates "#6 CYLINDER MISFIRE".

I replaced the sparkplug and sparkplug wires on that cylinder and checked the contacts in the distributor cap. Yet, I continue to get the same message.

I would greatly appreciate any advice or theories. Clogged injector?

Thanks!

Take number 6 spark plug wire off, place it next to the block. Turn the engine over, make sure its getting spark. If spark is there, swap a couple of injectors and see if the problem moves.
