If your BYD Tang’s check engine light flickers and the idle feels shaky, it’s often a sign of a misfire. Learn which sensors and parts to check first, and whether it’s safe to keep driving.
Understanding the Symptoms
A flickering check engine light alongside a rough idle usually points to an engine misfire. This means one or more cylinders aren’t firing properly, causing the engine to shake and the computer to send a warning. On the BYD Tang, a plug-in hybrid, the issue can be in the gasoline engine side—common on cars with higher mileage or neglected maintenance.
