Professional Engine Tune-Up Service

An engine tune-up restores lost performance, improves fuel economy, and ensures your vehicle starts reliably and runs smoothly. Over time, spark plugs wear out, ignition coils weaken, air and fuel filters clog, and carbon builds up in the intake and combustion chambers. A comprehensive tune-up addresses all of these issues and brings your engine back to factory performance levels.

Dr Auto Repair of The Palm Beaches provides thorough tune-up services that go beyond simply replacing spark plugs. We inspect and test ignition components, clean fuel injectors, replace filters, check timing and idle settings, and verify that all engine systems are operating correctly. Whether your vehicle has a traditional distributor ignition or a modern coil-on-plug system, we have the tools and experience to tune it properly.

Engine Tune-Up FAQs

How often should I get a tune-up?

Most manufacturers recommend spark plug replacement every 30,000 to 100,000 miles depending on plug type. Conventional copper plugs wear faster than iridium or platinum plugs. Check your owner manual for the specific interval for your vehicle.

Will a tune-up fix my check engine light?

If the check engine light is on due to a misfire caused by worn spark plugs or faulty ignition coils, a tune-up will likely resolve it. However, other issues can also trigger the light. We diagnose the fault codes first to confirm what repairs are needed.

How much does a tune-up cost?

It depends on your vehicle make, model, engine type, and how many spark plugs need replacement. V6 and V8 engines require more plugs than 4-cylinder engines. We provide an accurate quote based on your specific vehicle before starting any work.

Can I drive with a misfire?

You can, but you should not. A misfire causes unburned fuel to enter the exhaust system, which can damage the catalytic converter. It also reduces fuel economy and power. If your vehicle is misfiring, have it diagnosed and repaired as soon as possible to avoid more expensive damage.

What is the difference between a tune-up and diagnostics?

A tune-up is preventive maintenance performed at scheduled intervals to keep the engine running properly. Diagnostics is the process of identifying a specific problem after symptoms appear. If your engine is running poorly, we diagnose the issue first, then recommend a tune-up or other repairs as needed.

Do you work on all makes and models?

Yes. We perform tune-ups on domestic and foreign vehicles including 4-cylinder, V6, V8, and turbocharged engines. We use the correct spark plugs and follow manufacturer procedures for every vehicle.
