Here is what I would do. On a 100,000 service.
First clean the fuel system by adding either Sea Foam or Techron, follow the directions on the bottle. One full tank treatment is good, but I do two and I do not do any work on the engine till all the treated fuel is consumed.
Second when the tank is almost empty change fuel filter refill tank with premium fuel
Third change spark plugs, the current best is the NGK I believe. This is a good time to replace the wires too, may not be necessary but I would do it. Coils should be fine.
Fourth Replace air filter and clean MAF
Fifth change oil & filter
Sixth change coolant
Seventh change transmission fluid and filter.
Drive car and check for smooth stable idle as well smooth acceleration then check mileage on the highway you should be able to get 24-26 mpg if not.
Eight replace O2 sensors
Ninth exchange power steering fluid.
Tenth load test battery and replace if necessary.
Here is a good tune up read,
