Do you mean the exhaust smells like unburned fuel, or that you can smell fuel elsewhere?
Have you checked for ECM codes?
How many miles on your O2 sensor?

O2 sensors aren't worth two dead flies past 100,000 miles.
Code test tool (paper clip) & short pins E1 & TE1 together in the DIAGNOSTIC port next to the underhood fuse box. Turn key to ON position & count the blinks of the Check Engine light. it comes in 2 digit codes with a pause between each digit. More than one code continues in sequence. If steady blinking every half second, no codes are stored.
It's been documented about 100000 times....
