so you are saying that 19-20mpg, thats - the 1.2 or so thats off on the read out, is bad? thats about average for the v6. http://www.toyota-4runner.org/4th-gen-t4rs/54830-your-average-gas-mileage-v6-v8-welcome.html

id kill for 21.2 on my readout. So in reality its around 18.2 but still. Im averaging 16.
That would seem pretty low since EPA says 17/21 for the 4x4 v6...what about air filter, tire pressures, alignment, etc.?
I'd go with that stuff before I worried about a cat or plugs.
Fuel filter shouldn't be a problem since it's in tank, unless you run it below a quarter regularly.
for a v8 that doesn't seem off at all if you have a bit of a heavy foot...most of what I find for v8s says 15-19 is average.

that may be, but it would appear that since your mileage is looking to be correct, the 3rd cat can't be causing any issue...
I would imagine so long as there's no O2 behind the 3rd cat you can probably yank it without a problem, or get a simulator/spark plug non fouler to trick the rear O2 once you remove it and the truck will run fine.
