Use an OBD-II scanner to retrieve any trouble codes from the vehicle's computer, which will help identify the specific problem. Common issues may include oxygen sensor failures or ignition system faults. If you are unable to diagnose the issue, refer to the troubleshooting section of the owner manual or consult with a professional mechanic.
