Engine Diagnostics & Performance at Celso's Honest Auto Repair in Olathe, Kansas

A code reader tells you which circuit reported a problem. It does not tell you what failed. Our engine mechanical diagnosis and engine performance work in Olathe starts with the code, then verifies it with live data, mechanical testing and inspection before a single part gets ordered.

That matters because the same stored code can come from a failing sensor, a vacuum leak, a fuel delivery problem or something mechanical inside the engine. Replacing parts until the light goes out is how repair bills get out of hand. We'd rather spend the diagnostic time up front and hand you one accurate answer.

Bring it in for a steady or flashing check-engine light, a rough idle, hesitation under acceleration, hard starting, a noticeable drop in fuel economy, or any new noise from under the hood. If the light is flashing, drive gently and call us — that usually signals a misfire that can damage the catalytic converter.

Once we know what's wrong you get the finding, the fix and the price before work begins, including what's urgent versus what can safely wait. Call (913) 850-1750 to get your vehicle scheduled.
