Tune up is kind of vague...I usually invision a tune up as every 30K
1. Change all filters (oil of corse every 3K, Fuel, air, micofiber{a/c})
2. Spark Plugs (check wires)
3. Flush fluids (transmission, coolant, steering, etc.)
4. Lube the chasis (heh heh, i said lube)
5. Have a beer
-I'm sure I'm leaving out some stuff, but that should get you started.
