Is 12.24 to 1 to Rich or is it fine to run it like that cause I thought 13.5 - 15 to 1 is the proper air fuel ratio?

It depends on the Setup of your vehicle and under what load you are seeing this AFR.

if you run 12 -11 your spark plug will not last +you wash-off that protective layer of oil in cylinders.
I recommend you check the spark plug to see the fuel mixture sometime one injector can cause your AF to go to12-11.
