“Expecting the worst but Edward and Caleb were great and found it only needed a proper trans service that another shop said they did but left seriously underfilled.”
What's going on
The check engine light means your vehicle's computer detected something outside normal operating range. It might be minor — a loose gas cap — or it might be a misfire, emissions fault, or sensor issue that gets expensive if ignored.
Symptoms
- Solid check engine light with normal driving feel
- Flashing check engine light (often misfire-related)
- Rough idle, hesitation, or reduced power
- Poor fuel economy or new smells from the exhaust
- Light appeared after filling with gas or after a recent repair
Can I keep driving with the check engine light on?
A steady light and normal driving usually means you can drive carefully to a shop for diagnosis soon — but don't ignore it for weeks.
A flashing check engine light often indicates an active misfire that can damage the catalytic converter. Reduce load, avoid highway speeds, and get it checked as soon as possible.
If the light is on with severe shaking, overheating, or oil pressure warnings, stop driving and call the shop.
Common causes
- Loose or failed gas cap (evaporative emissions)
- Oxygen sensor or catalytic converter efficiency codes
- Ignition misfire — coils, plugs, or injectors
- Mass airflow or intake leaks
- Transmission or other systems requesting a warning
