Engine Diagnostics & Performance Testing in Rochester & Winona, MN | Joe’s Auto & Tire
Loss of power? Rough idle? Stalling or misfiring? We’ll find the root cause.
Your engine is the heart of your vehicle—and when it’s not performing right, you feel it. Whether it’s reduced power, unusual vibrations, rough starts, or engine noise, these symptoms often point to deeper issues that go beyond a simple check engine light.
At Joe’s Auto & Tire, we offer engine-specific diagnostics and performance testing in Rochester, MN and Winona, MN to pinpoint and repair internal engine problems quickly and accurately.
What Is Engine Diagnostics?
Unlike a basic code scan, engine diagnostics involves hands-on testing of the components that affect engine combustion, airflow, and fuel delivery. We look beyond the codes to:
- Investigate performance complaints (power loss, stalling, hesitation)
- Test ignition system components (plugs, coils, timing)
- Analyze fuel delivery and injector performance
- Inspect airflow systems (MAF sensor, intake, throttle body)
- Check internal engine health (compression, vacuum, leaks)
Modern engines are highly complex—and misdiagnosing a drivability issue can lead to wasted time and money. That’s why our ASE-certified techs use a structured, professional approach to every engine concern.
