Your car’s fuel and ignition systems are designed for years of trouble-free operation, but eventually need a “tune-up.” Signs that it might be time for a tune-up include:
- Check engine or service engine lights.
- Decreased gas mileage.
- Reduced engine power.
- Stalling, knocking, or running rough.
If you own an older vehicle, a tune-up can:
- Boost engine performance.
- Improve gas mileage.
- Ensure reliable starts.
- Reduce harmful emissions.
Today’s vehicles can benefit from a tune-up anywhere between 60,000 and 100,000 miles. Your owner’s manual provides additional guidance.
What's a Tune-Up These Days?
Before electric ignition, fuel injection, and computer control, a mechanic would “tune” your car engine as if it were a musical instrument, adjusting the ignition timing, idle speed, and fuel/air mixture. Today, Monro auto technicians will inspect and/or replace the:
- Air and fuel filters.
- Spark plugs and spark plug wires.
- PCV (positive crankcase ventilation) valve.
And, clean the:
- Fuel system—fuel injector, intake valve, combustion chamber.
- Air intake system—throttle body, throttle plate.
We use the Valvoline Performance System™ 3-Step Fuel and Air Intake Cleaning System
. Depending on the engine design, some older vehicles might require additional parts and work, including replacement of the distributor/distributor cap, rotors, points, and condensers.
