Default would this be a symtom of a bad injector?

I've noticed my EGT's being pretty high latley
around ~755 while cruising (in the past it was around ~670)

Also my AFR looks funny,
while holding the car at 3,000 rpm or any set rpm for that matter on a flat road at a steedy speed. The AFR would jump between 13.5 to 14.7
In the past the AFR oscillation was maybe a .3 variance.
Mind you this is at a set speed and rpm on a flat road...

Seeing these 2 symptoms makes me suspect a clogged/bad injector. I'm just making an educated guess here...

what do you guys think?

not sure, I usually never pay attention to it as it's hard for me to get an accurate mesaurement here in the city.
Daytime driving with stop and go bumper to bumper traffic really throws it off alot
