Common questions
Is it safe to drive with the check engine light on?
A steady light usually means you can keep driving for a short time, but have it checked soon. A flashing light means the engine is misfiring: slow down and get it looked at as soon as you can, because driving on a misfire can damage the catalytic converter.
Why not just get the code read for free?
A trouble code tells you which system reported a problem, not which part failed. Diagnosis means testing to confirm the cause, so you don't pay for parts you didn't need.
