How to Identify and Fix a Rough Idle in Your Car?

Identifying and fixing a rough idle in your car is essential to ensure smooth performance and prevent further damage. A rough idle occurs when your engine doesn't run smoothly while the car is stationary, often leading to noticeable vibrations. One common symptom is when a car shakes at idle but smooths out while driving. This can be caused by various issues, such as dirty fuel injectors, a malfunctioning oxygen sensor, or worn spark plugs. To fix a rough idle, start by inspecting these components. Clean or replace dirty fuel injectors and check the oxygen sensor for proper operation. Worn spark plugs should also be replaced, as they can lead to misfires and uneven engine performance. Regular maintenance, such as timely oil changes and air filter replacements, can prevent rough idling. If the problem persists, it’s best to consult a professional mechanic to diagnose and resolve the underlying issue effectively.
