The O2 sensor will definitly knock 2-3 mpg off.
So will a clogged filter.
...and a leaky fuel line.. :]

I also wonder what tires your running. Stock or lifted with larger wheels.
Leaky vacuum lines can also cause your engine to run a bit higher RPM
at idle. Not sure if it changes milage by that much though, usually just
makes things a bit rough.

Re: BAD GAS MILAGE
And my `96 Cherokee 4.0L usually gets 20 MPG highway, the same mileage
as my `89 Cherokee 4.0L got. Running in Full-time 4WD reduces it a bit.
Among other useful things that "pond jumper" might do is to sniff near
the left rear wheel for gas fumes. If he smells any at all he should
check his long-neglected fuel filter for rust-through and leaks.
