In an effort to improve gas mileage...
since 15.4mpg doesn't seem to good compared to the rest of you guys, I'll try the following.
1. Seafoam it - I've heard great things, why not try it?
2. Change the oil - 5w-30 - synthetic or no? I'm not sure what the PO used.
3. Change the spark plugs - NGK BKR-6EIX
4. Change the spark plug wires - NGK TE119
5. Air filter - K&N - Lexkost mod, if it's not too noisy for my tastes.
6. Change the fuel filter.
7. Distribution caps? - Worth it?
8. Clean the throttle body.
If that doesn't work...
9. Change the injectors.
10. Change the O2 sensors.
Tell me what you guys think. Any input is appreciated!

1) I assume you mean through a vacuum line. Do it. Cheap but maybe not so effective.
2) 5W-30, synthetic or not is more of a preference. A high quality dino should do fine. With that said, I use Mobil 1 EP 5W-30.
3) NGK or Denso, platinum or iridium will work fine.
4) I recommend using OEM wires.
5) I personally don't trust K&N's ability to filter fine particles. I'd stick with the OEM airbox and a genuine Toyota air filter.
6) This won't affect mileage unless your filter is clogged, so I'd skip it.
7) Worth it when you're changing the plugs and wires. Change the caps and rotors.
8) Definately.
9) A bit drastic and most definately unnecessary.
10) Check yours first as new ones may or may not affect your mileage.

I've done everything listed except 9 and 10, and I haven't changed the fuel filter.
I get about 17-18mpg average on a tank, or about 320-350 miles on a tank, depending on how much freeway driving I've done. In the Bay Area, you get a good mix. I woudln't say 50/50, maybe like 70/30 in terms of mileage, and the opposite in terms of actual time on the road =P

Wow!

I just got my license and have a 94 es 300, and I get 19.5 city. Thats just school, work, home, school, work, home. I would definitely get that checked out..

You may want to check the o2 sensors first- not last on the list.
Most importantly- train your foot. Most loss in MPG comes from heavy foot.
Why are we comparing rotten apples to ripe oranges?
