You can always test the wide band.
Take your wide band out of the exhaust but leave everything hooked up, then take a rag and spray some brake cleaner on it, turn your key on (to the let the wide band do it's warming and whatnot), now the wide band should read Stoich. After that, wrap the rag (that you sprayed the brake cleaner into) and the gauge should start slowly reading rich. If not, you have a bad WBo2

Also you have ot remember, WBo2's are like flurescent (sp??) lights, they just don't die right away, they slowly die away.
AEM sells the replacement for 80 bucks or so.

I was told immediately that the AEM sensors would start doing this after a while. So i picked up a spare for such an occasion. Mine hasn't started yet, but from what I was told this sounds like the culprit. I got mine from Jegs i believe. You should replace it and possibly get a spare if you can $pare it.

update:
I swapped in the other injectors and no change, still same issue being reflected on wideband or being with wideband.
I'm thinking the next thing to do is replace the wideband 02 sensor. Any other ideas or confirmation on this before I start spending money on parts I didn't need would be great.

Oops I guess I wasn't clear on this point...the injectors running too rich can simply precipitate the sensor going bad before its time...changing clogged injectors with good ones won't make the problem go away, just keep it from happening to a new wideband sensor if that is the problem.

Update:
Good news, problem resolved. It was the WB02 sensor. It makes sense and am very happy to be able to keep my car in accurate tune once again. I knew that if this didn't fix the problem that I may be chasing my tail for a wile so its a relief.
Thanks for all your input/suggestions on this guys, you were helpful
