What Your Check Engine Light Is Trying to Tell You

Diagnostic Services at Weldon Spring Auto & Tire

Seeing your check engine light come on can be stressful, but knowing what it means and how to respond can help you avoid bigger problems down the road. At Weldon Spring Auto & Tire, we’re here to guide you through what to do when that warning light appears.

If your check engine light is flashing, it’s a sign of a serious issue that could cause severe damage—often to your catalytic converter or other critical components. When this happens, avoid driving at highway speeds, towing, or hauling heavy loads. Take it easy on your vehicle and head straight to Weldon Spring Auto & Tire for an inspection.

If the check engine light is steady (not flashing), keep an eye on how your car feels for a day or two. Notice if the engine feels like it’s missing, sluggish, or hesitating during acceleration. If the light stays on and you detect any of these symptoms, it’s time to schedule an appointment with us.

When you come in, our technician will connect a diagnostic scanner to your vehicle’s onboard computer to read the trouble codes stored inside. These codes help pinpoint the likely cause of the problem and give us a starting place for further diagnostics and repairs.

Don’t ignore that warning light—give Weldon Spring Auto & Tire a call today. We’ll set up a convenient time to check your vehicle and keep it running safely and smoothly.
