Frequently asked questions
How much is a diagnostic fee?
Initial code scan is free. Full diagnostic time is $99 and credited toward repair if you have it done with us.
Is it safe to drive with the check engine light on?
Solid light: usually yes, get it checked soon. Flashing light: stop driving — active misfire can destroy the catalytic converter.
Will you tell me exactly what's wrong?
Always. You get a written diagnosis with the part, the test results and the repair quote.
