DO YOU NEED AN EMISSIONS TEST OR A SMOG CHECK?
Vehicle emissions testing is required in certain states to help reduce air pollution and ensure your car is running efficiently. If your vehicle is due for testing or showing signs of an emissions issue, it’s important to have it checked.
- Check engine light is on
- Failed a recent emissions or smog test
- Decreased fuel efficiency
- Rough idling or poor engine performance
- Excess exhaust smoke or strong odors
- Trouble starting or stalling
Safety Note: If your check engine light is flashing, or your vehicle is running poorly or stalling, more serious engine or emissions system issues may be present. Continued driving could lead to further damage, so have your vehicle inspected by a Firestone professional as soon as possible.
