Questions & answers

Check Engine Light Diagnosis FAQs

If the light is steady, the car is usually safe to drive to us soon for a scan — but if it’s flashing, that signals an active misfire that can destroy your catalytic converter, so stop driving and call us. Either way, don’t ignore it; small issues get expensive fast.
Yes. A flashing (not steady) light means a severe misfire is dumping raw fuel into the exhaust, which can ruin an expensive catalytic converter within minutes. Reduce speed, avoid hard acceleration, and get it looked at immediately.
We perform a full diagnostic scan and — unlike a parts-store code read — we interpret the live data and pinpoint the actual failing part, not just the generic code. That means you fix the real problem the first time instead of guessing.
A light that clears on its own often means an intermittent fault (like a loose gas cap or a sensor acting up) — but the stored code remains in the computer. We can read that history and catch the problem before it comes back worse.
No — an illuminated check-engine light is an automatic emissions-inspection failure in Texas. Bring it in and we’ll diagnose and repair the cause so you can pass and stay road-legal.
We give you a clear diagnostic quote up front with no surprises, and qualifying repairs are backed by our 2-year / 24,000-mile nationwide warranty, with financing through Affirm and Sunbit.
