Diagnostics & Maintenance
OBD-II scanning, check-engine-light diagnosis and scheduled service.
Check-engine light? Odd noise? Hesitation, misfire, rough idle? We pull the codes with a professional scan tool, run the right tests, and explain in plain English what's actually going on — not just what the code says.
Codes are a starting point, not an answer. A P0420 doesn't always mean a catalytic converter — it can be an upstream O2 sensor, an exhaust leak, or a timing problem. We diagnose the cause, not the symptom.
We also handle scheduled 30/60/90k maintenance — fluids, filters, plugs, belts and inspection items, all to your manufacturer's spec.

Frequently asked
What's the difference between a scan and a diagnosis?+
A scan reads codes (most parts stores will do this free). A diagnosis confirms what's actually causing the code, which is what you need to fix it once and not twice.
How much is a check-engine-light diagnosis?+
We charge a flat diagnostic fee that's credited toward any repair we do. No surprise bills.
Will you tell me if it's not worth fixing?+
Yes — if a repair is more than the car is worth, we'll say so. Honest advice, even when it costs us a sale.
