Thanks Manny,

I'll try replacing the oxygen sensor since they are cheap.

Most O2 sensors die a slow death. Think of it as a battery wearing out, i.e. voltage goes lower & lower.
As this begins to happen, the ECU will interpret this as having to add more fuel.
Once you reach the adaption limits, a CEL will come on.
I don't see why any 4-wire O2 should not work. Just match the wires correctly ( 1 signal wire, 1 power wire for the heater element, and 2 ground wires ).
You could also backprobe the signal wire & see what the voltage output is & how " lively " the sensor is.
These are generic suggestions applying to O2 sensors in principal.
