Why does the car idle rough but drive smoothly?

A car idling rough can be a symptom of several different engine-related issues. The most common cause is an imbalance in the air-to-fuel ratio, which can be caused by a clogged air filter or fuel injector. It can also be caused by a vacuum leak, which allows too much air into the engine and prevents it from running smoothly. In some cases, a car will idle rough because of an issue with the ignition system, such as a spark plug that is fouled or damaged. If the idling problem is severe, it can also be caused by engine damage, such as a blown head gasket or cracked cylinder head. If you're experiencing car idling problems, the best course of action is to take it to a qualified mechanic for diagnosis and repair.
