Restore Power, Efficiency & Reliability with a Professional Tune-Up
If your vehicle feels sluggish, noisy, hesitant, or just “off,” it may be asking for a tune-up. At By The Book Diesel & Auto Repair, our technicians perform complete tune-up services designed to restore engine performance, fuel efficiency, and overall dependability — no matter what you drive.
Today’s vehicles are far more advanced than older models that required tune-ups every 10–20k miles. Many newer cars can go 80k–100k miles before certain components need attention, but routine maintenance and early warning signs should never be ignored. A tune-up is one of the most effective ways to prevent breakdowns and avoid costly repairs later.
What’s Included in a Tune-Up?
A tune-up at our shop goes far beyond spark plugs. We focus on the entire engine performance system, including:
- Ignition components
- Fuel delivery system
- Intake and airflow
- Sensors and electronics
- Filters and fluids
We also inspect your vehicle top-to-bottom during each visit, helping you catch small issues before they turn into major problems.
9 Signs You May Need a Tune-Up
- Warning Lights: Check engine lights or service indicators point to a problem that needs immediate attention — anything from a faulty sensor to a failing transmission component.
- Stalling: Sudden stalls during acceleration or at idle can indicate fouled plugs, clogged filters, or fuel delivery issues.
- Hard Starting: If it struggles to start or won’t stay running, it could be the battery, starter, ignition system, or sensors.
- Poor Fuel Mileage: A noticeable drop in fuel economy means the engine isn’t running efficiently — often a spark, fuel, or airflow issue.
- Soft or Noisy Brakes: Not directly part of a tune-up, but often discovered during inspection. Any change in brake feel or noise is important to address quickly.
- Unusual Noises: Squealing belts, knocking, pinging, or grinding sounds point to problems in the ignition, steering, belts, or suspension.
- Rough or Delayed Shifts: Hesitation, slipping, or harsh shifting means your transmission needs attention before the problem escalates.
- Sluggish Acceleration / Loss of Power: If it feels weak or unresponsive, the issue may be fuel delivery, sensors, ignition, or restricted airflow.
- Vibration: Shaking in the wheel, seat, or floorboard often indicates worn tires, balance issues, failing bushings, or driveline problems.
