What items are typically serviced during a high mileage tune-up besides the following?  I have heard there are some non-typical adjustments (computer related perhaps) that the better more experienced mechanics perform.  Any experience with this?

  a.. Oil & filter
  b.. Plugs & wires
  c.. Cap & rotor
  d.. Timing adjustment
  e.. Coolant & thermostat
  f.. Fuel filter
  g.. Air filter
  h.. O2 Sensor
Thanks,
Chris
