Will a throttle body spacer do anything to my truck? It's a 97 4.2l v6. I mainly want better mpg

No, they are a cheap gimmick. Get a CAI and a tuner

if you haven't done a good tune up, if suggest that. Also checking the small things like tire air pressure, and filters and such, like fuel filter air filter can help free up some wanted MPG

Proper maintenance, driving habits, and driving conditions (city/highway) will have the most impact. Tune everything up and keep your foot out of the gas and that's as good as you're going to get within a couple of miles per gallon. A truck "is what it is" when it comes to gas mileage...don't expect anything earth shattering.

I just averaged 22.4mpg with my 2010 4x4 5.4 over a 200ish mile trip. I babied it and kept it at 59mph. I did stop for pizza twice and gas once. I Kept off the brakes and tried to time the lights. Not hard to do on a 55mph road, but would've killed me on the interstate. Just like my Fx35, I "could" get 25 mpg, but the way I drive it I get 18 mpg

Apples to oranges, the OP has a '97.
