I have a 2001, which also has 4. I only did the two upstream sensors before the cat. To be fair I go the 21 mpg's in Colorado where the air is thinner. I did get around 20 on a trip to northern Michigan a couple of weeks ago.

No its not stock, but good question, its all in the set up. I'm running a 2" OME lift with 245/75/16 Goodyear Duratrac tires (load range C), 3:55 Gears, and a set of 4 hole Fuel Injectors. I didn't want to go any higher than that because of the drive line angle issues. Mine is a daily driver, so I wanted to maintain fuel economy and driveablity.

alright mine lifted 4" with a TC drop on 32x11.50 tires. thinking of getting new fuel injectors or taking mine out and soaking them in seafoam and then getting new 02 really soon
