My car has a strange problem i cant seem to figure out. When i first start it, it will idle fine, at around 14.7 to 15 afr, but as the car warms up it start to get rich, normally stopping at around 12.5ish. I have tested the water temp sensor it is fine and the o2 sensor doesn't seem to be changing anything when its plugged in or not. but that wouldn't explain why its starts getting rich as it warms up since the o2 sensor doesn't do anything till around 160 degrees. Has anyone had similar problems or have any ideas?

One side note. If i blip the throttle itll go rich but then jump up to 14.7 to 15 and stay there for around 10 seconds , maybe 15.
