Zeekr 007 Rough Idle & Flickering Check Engine Light: What's Going On?

Why Does the Check Engine Light Flicker?

When the check engine light flickers intermittently and the idle feels rough, your Zeekr 007 is telling you that the engine is misfiring — meaning one or more cylinders aren't firing properly. A steady light often means a smog or sensor issue, but a flashing or flickering light is more urgent. It signals that unburned fuel is entering the exhaust, which can damage the catalytic converter if ignored.

Likely Culprits to Check First

• Ignition coils and spark plugs — The most common cause of rough idle and misfire. On the Zeekr 007, check for cracked coils or worn plugs, especially if you're near 30,000–50,000 miles.
• Vacuum leaks — A cracked intake hose or loose PCV line can lean out the air-fuel mixture, causing a rough idle and intermittent codes.
• Mass airflow (MAF) sensor — If it's dirty or failing, the engine gets wrong air readings, leading to stumbling and a blinking light.
• Fuel system issues — A clogged injector or weak fuel pump can starve a cylinder, especially at idle.

Is It Safe to Keep Driving?

Short answer: no — not for long. If the light is flickering, the engine is actively misfiring. Driving like this risks overheating the catalytic converter and causing costly damage. You can limp to a safe spot or a nearby shop, but avoid heavy acceleration and long trips. Have the codes read as soon as possible (even a basic OBD-II scanner will show which cylinder is misfiring). The Zeekr 007's hybrid system may also behave oddly, so be gentle with it and get it checked promptly.
