I have one more issue now though. After I drive the car and do not let it fully cool off before I drive it again. It will run rich just cruising around in the 13.5 - 8 range. After a few minutes it goes back to normal.
Could that be a bad front 02?
Yes, and make sure to get a Denso o2 and not a Bosch. I had a new Bosch unit and it went bad in under 15k miles with just over 1 year in the car.
