Check Engine Light & Diagnostics
A code tells us where to start looking, not what to replace. We test until we find the actual cause, then explain it in plain language so you can decide.
- ASE Master Certified technician on the diagnosis
- Photos and test results sent to your phone

Common questions
The light is on but the car drives fine. Is it urgent?
A steady light means get it checked soon. A flashing light means an active misfire that can damage the catalytic converter, so stop driving and call us.
Can't you just read the code and tell me the part?
A code points at a circuit or system, not a part. Replacing whatever the code names is how people buy parts they did not need. We test to confirm the cause first.
What does a diagnosis cost?
It depends on how deep we have to go, and we tell you before we start. If a repair follows, you get a written estimate to your phone and approve it first. Call for a quote.
