With an '01 truck with that few miles my guess is that you will find
that the )2 readings should be off. Also, I'd bet that your plugs are
glazed if you drive a lot of small, short trips keeping the truck from
reaching 220 degrees. You'll probably be in need of the "top down"
cleaning that a certified GM dealer can do to remove all of the
deposits from the inside of the engine.
As far as MPG, you never stated what motor and gear ratio you have.
Also, doing a lot of small intown trips will slowly make your MPG go
down. My '01 Silverado has the 5.3 with the 3.43 ratio and about 72k
miles on it now. The only mods I've done was add a fresh air intake
and replaced the tranny fluid with Mobile 1 synthetic. On my trip to
Florida a few years ago I average 22MPG on the highway.
