What is a car tune-up?

The concept of a car tune-up comes from the days when cars literally needed to be fine-tuned by someone with the ability to listen to and “feel” changes in engine performance to operate at their best. Today, however, the term “tune-up” refers to a more thorough maintenance inspection rather than a lot of fiddling under the hood. Here is what to expect from a modern tune-up.

Performance Checks

Your mechanic will run checks on your car’s major systems to ensure that they are operating within the manufacturer’s specifications. These include:

  • Battery voltage
  • Power balance
  • Engine vacuum
  • Fault codes
  • Emissions
  • Fuel feedback control loop
  • Idle speed
  • Computer data analysis


A few car parts still need to be replaced occasionally. Based on the manufacturer’s recommendations and the car’s mileage, your mechanic might replace:

  • Spark plugs
  • Filters
  • Ignition wires (When present)
  • Ignition coils (When problems are found)
  • Fuel injectors (When problems are found)

Cleaning / Servicing

To keep your car’s engine performing at its best, your mechanic might clean:

  • Fuel injectors
  • Induction and fuel system servicing
  • Throttle body
  • Crank case vent system service
