Why does my Tiggo 4 idle roughly o r sputter at low speeds?

Rough idling o r sputtering at low speeds is often caused by vacuum leaks, a dirty throttle body, o r issues with the idle air control valve. Fuel mixture problems o r malfunctioning sensors like the mass airflow sensor can also disturb engine performance at idle, leading to sputtering. Observing RPM fluctuations and engine behavior can help identify the issue.

Rough idling o r sputtering at low speeds can result from:

Vacuum leaks in hoses o r intake manifold.

Dirty throttle body o r malfunctioning idle air control valve.

Fuel mixture problems o r faulty sensors such as the mass airflow sensor.

Cleaning the throttle body, repairing vacuum leaks, and checking sensor performance can correct these problems.
