Need a solution to an issue before i burn the car.....

1. Car was running fine. Tune was excellent
2. Car is starting fine when cold but goes to idling RICH 10 - 11afr.
3. Cruising is fine at 14 -15 afr but soon as lift of gas to slow down or stop goes back to rich .

5. ALL sensors on engine have been replaced (coolant temp, map, maf, both cam sensors, crank sensor, iat, front o2)
6. CEL only shows system too rich error
