Introduction
The phrase "tune-up" comes from a time when mechanics adjusted carburetors and ignition timing by hand. Modern engines are computer controlled, so today's auto tune up service focuses on replacing wear items on schedule and checking that the engine is running the way it should. Here is what that usually means for your car.
Spark plugs and ignition coils
Spark plugs wear gradually and have a manufacturer-specified replacement interval. Worn plugs can cause hard starts, rough idle, misfires and lower fuel economy. Spark plug replacement is the core of most tune-ups. When a misfire points to a failing coil, ignition coil replacement may also be needed.
Filters and fuel system
A clogged engine air filter restricts airflow, while a dirty cabin air filter affects the air you breathe inside the car. Some vehicles benefit from fuel system cleaning when deposits affect performance. See our guide on engine vs. cabin air filters.
Diagnostics come first
If your check engine light is on or the engine runs poorly, a diagnostic computer scan reads stored trouble codes and live data. A code points to a system, not automatically to a part, so testing confirms the cause before replacing anything. Learn more in our diagnostics and tune-up category.
Signs your vehicle may need a tune-up
Common signs include rough idle, hesitation when accelerating, hard starting, a flashing or steady check engine light, reduced fuel economy and engine misfires. Belts and hoses are worth checking at the same time; see serpentine belt replacement.

Common questions
How often do I need a tune-up?
There is no single interval. Follow the manufacturer's schedule for spark plugs and filters, and have the vehicle checked any time it runs poorly or the check engine light comes on.
Will a tune-up fix my check engine light?
Only if the cause is related to the parts replaced. We scan and test first so the repair matches the actual problem.
Do you work on most makes and models?
We service everyday cars, SUVs and light trucks. Call with your year, make and model to confirm.
