Advanced Engine Tune-Ups
Comprehensive service to improve engine smoothness, power, and fuel efficiency.
Modern Tune-Up Service
The traditional 'tune-up' has evolved. Today, it's less about replacing predetermined parts and more about precision system optimization. Our modern tune-up care focuses on restoring engine efficiency and performance through comprehensive evaluation and targeted component replacement. We test ignition coils, inspect spark plugs, clean fuel injectors, and ensure all engine management sensors are providing accurate data. This care is ideal for vehicles experiencing rough idles, hesitation, or reduced fuel economy, bringing them back to peak operating condition.

Ignition System Service
A strong spark is essential for efficient combustion. We test the entire ignition system, from the battery and cables to the coils and spark plugs. Worn plugs or weak coils can cause misfires, wasting fuel and increasing emissions. We replace spark plugs with the specific type and heat range required by your engine, ensuring a perfect burn. For older distributors, we can adjust timing and points. This precise service ensures consistent starts, smooth operation, and maximum power output from every drop of fuel.
Fuel System Cleaning and Service
Over time, fuel injectors can become clogged with deposits, disrupting the fine spray pattern needed for optimal combustion. We perform trusted fuel system cleaning cares that remove these deposits from injectors, intake valves, and combustion chambers. This restores lost power, improves throttle response, and can significantly enhance your miles per gallon. For carbureted classics, we offer ultrasonic cleaning and rebuilds. Let us optimize your fuel delivery for smoother performance and better efficiency.
