Why is my Tiggo 4 misfiring o r running rough at idle?

Misfires o r rough idling often indicate a faulty ignition coil. A weak o r failing coil can fail to provide consistent spark to the spark plugs, causing uneven combustion. This is more noticeable at low speeds o r idle. Observing whether the misfire occurs in one cylinder o r randomly can help identify which coil o r spark plug may be failing.

Misfires o r rough idling are often caused by a faulty ignition coil. A weak o r failing coil cannot provide a consistent spark to the spark plugs, leading to uneven combustion. This is especially noticeable at low speeds o r when the engine is idling. Inspecting each coil and spark plug can identify the faulty component.
