Ok stuff that can cause loss of power and low gas mileage,also stuff that needs to be maintained over certain amount of mileage. This is what I can come up with so far, correct whatever is wrong.

[U]Maintanence: [B]Miles
Oil Change: 3000 Miles
Air Filter Cleaned: Don't know
FuelFilter Change: Don't know
Spark Plugs: I say once a year?
PVC Valve: Don't know
Belts: I say about 50kMiles?
Coil Packs: Are these a maintanence part?
Clean Throttle Body: Guess whenever you do air fliter cleaning?

Please help me out on anymore things for maintaining my car and keeping mileage good and loss power restored.
