Tune Ups

A tune-up (also known as a major service) is regular maintenance performed on an automobile, or more generally, any internal combustion engine. Most automobile manufacturers recommend a tune-up be performed at an interval of 30,000 miles (48,000 km) or two years, whichever comes first.
A tune up may include inspection and/or replacement of the following components:

  • Spark Plugs
  • Distributor Rotor
  • Distributor Cap
  • Oxygen Sensor
  • Fuel Filter
  • PCV (positive crankcase ventilation) Valve
  • Replace spark plugs
  • Check choke, engines with carburetors
  • Check compression and power balance, identifies bad fuel injectors as well as compression problems
  • Replace PVC value
  • Check timing, adjust if necessary
  • Check manifold intake, reveals exhaust restrictions
  • Check all emission controls, EGR valve, air pump, etc.
  • Check ignition wires, replace if necessary
