Tune Ups


A Tune-up provides preventative maintenance, while identifying and replacing worn parts. They ensure that your vehicle will operate at optimal conditions by maintaining the ideal conditions for normal car operation. Neglecting these basic tasks could result in low gas mileage and damage to critical engine components.

Most cars require regularly scheduled tune-ups around every 30,000 miles, and major maintenance at 60,000 miles. Some newer vehicles may not even require a tune-up until 100,000 miles. Check with your manufacturer or an Ernie’s Auto Service technician for what is correct for your vehicle.

A thorough tune-up will include:

  • Replacing the air filter
  • Replacing the fuel filter(s)
  • Installing new spark plugs and replacing any worn spark plug wires
  • Inspecting and installing a new distributor cap, if one is needed
  • All fluids checked and topped off
  • A battery check and terminal cleaning, if necessary
  • A positive crankcase ventilation (PCV) valve replaced, if clogged

In addition, cars built prior to 1979 have additional requirements. Cars without an electronic ignition require changing the points and condenser. Cars with electronic ignition should have the timing checked.

Fuel injected cars need to have the throttle plate cleaned and/or adjust the air-fuel mixture. Cars with carburetors may need additional adjustments.

Maintaining a regular tune-up schedule will ensure your car’s longer life, better gas mileage and performance. Call Ernie’s Auto Service today for an estimate and appointment.
