Car running RICH during warm up (pops in exhaust)

[Jbrews]

my 2004 base 986 is having a small issue. After cold start, there are pops in the exhaust (igniting fuel), but after the car idle settles (warms up), it runs fine. I have check secondary pump and it is working fine. Any ideas what would cause this? I assume if it was a plug or coil pack, it would do it after warm up as well. Car runs really well once warm.

Checked live stats and 02 sensors are running close to zero (up and down some but basically zero). HELP??

I have also noticed the oil smells of gas when the oil fill cap is removed. Leaky injector?

Throttle body cleaned and MAF sensor replaced. No change.
