About Engine Diagnostics & Check Engine Light

Common questions and tips from our work with Egg Harbor City customers.

Is it safe to drive with my check engine light on?
A steady light usually means you can drive a short distance, but a flashing light points to a serious misfire that can damage your catalytic converter. When in doubt, call us before driving far around Egg Harbor City and we will tell you whether to bring it in right away.
Why does the code reader at the parts store give a different answer?
A free code read only points to a system, not the exact failed part. We use that code as a starting point, then test the actual components so you pay to fix the real problem once instead of replacing good parts based on a guess.

Tip

Don't ignore a small warning

Many check engine codes start small, like a loose gas cap or a weak sensor, and stay cheap if caught early. Letting them run for months often lets a minor fault snowball into a major repair, so get it scanned soon.
