General Noise (Idle) - Noises & Vibration Symptoms
Common symptoms and diagnostic guides.
Sometimes engine sounds uneven idle
An uneven engine idle often signals issues with ignition, fuel delivery, air intake or sensor systems, causing rough idle and vibrations while idling. Early diagnosis prevents further engine damage.
Engine sounds off then okay
An engine that sounds off initially then becomes normal is often due to cold?start issues, sensor problems, or air/fuel imbalance that corrects as the engine warms up.
