Steady vs. Flashing Check Engine Light: What It Means

A steady check engine light means the engine computer has logged a fault that should be diagnosed soon. A flashing check engine light signals a more urgent problem, such as an active misfire, that can damage your engine if you keep driving. Whether the light is steady or flashing, we recommend bringing your vehicle to Boise Muffler Auto Repair as soon as possible.

Our Check Engine Light Diagnostic Process

Our check engine light diagnostic goes well beyond reading a code. Every visit follows four steps.

01 OBD-II Scan

We connect professional-grade equipment for an OBD-II scan that reads the fault codes stored in your vehicle’s computer.

02 Code Interpretation & Pinpoint Testing

A code identifies a system, not a failed part. We interpret it and run pinpoint tests to confirm the root cause before recommending repairs.

03 Clear Findings & Recommendations

We explain what we found in plain terms and provide recommendations and an estimate so you can decide how to proceed.

04 Repair & Verify

We complete the repair, then verify that the check engine light stays off.
