That's what I've been calling my 95 4Runner lately. It's fine on flat freeways, but I live in the mountains, and it's just terrible. Any hills at all and it's hunting for a gear and gets 11mpg if I'm lucky (on the freeway it gets maybe 14).

Bottom line: What can I do to get better mileage and better driveability?

Background: It has about 118k on it, 33x10.50's, 4 inch lift, 3 liter v6, a K&N air filter and a Flowmaster cat-back exhaust. The p.o. didn't change the gearing when he put the 33's on it, claiming he didn't need to. Maybe down in the valley, but up here, it's a pig.

4Wheel Parts suggests 4.56 or 4.88 gears. Any thoughts? I'm also going to do a full tuneup including plugs, clean the mass airflow sensor, and replacing the fuel filter. Anything else I can do? Help - otherwise this thing will be for sale soon...
