Why Does My Car Shake at Idle? | Grand Garage
Is your car shaking when it’s idling? At Grand Garage, located at 1556 E Grand Ave, Escondido, CA 92027, we understand how frustrating and concerning this issue can be. Your car should run smoothly, and excessive vibrations at idle often indicate an underlying problem that needs attention. With decades of experience in automotive repair, our team is here to help you identify the cause and get your vehicle back to optimal performance.
Common Causes of Car Shaking at Idle
When your car shakes at idle, it’s often a sign that something isn’t functioning as it should. Here are the most common culprits:
1. Engine Misfires
A misfiring engine can cause your car to shake. This happens when one or more of the cylinders fail to ignite properly. The reasons for misfires can include:
Worn Spark Plugs: If your spark plugs are old or damaged, they may not ignite the air-fuel mixture efficiently.
Faulty Ignition Coils: These deliver power to your spark plugs, and any malfunction can lead to misfires.
Clogged Fuel Injectors: If fuel injectors are dirty or blocked, they may not deliver the right amount of fuel to the engine.
2. Vacuum Leaks
Your engine relies on a carefully balanced air-to-fuel ratio. If there’s a vacuum leak, extra air enters the system, causing an imbalance and leading to rough idling. Vacuum leaks are often accompanied by a high-pitched hissing noise.
3. Dirty or Faulty Throttle Body
The throttle body controls the amount of air entering your engine. Over time, it can become clogged with carbon deposits, disrupting the airflow and causing shaking at idle.
4. Worn Engine Mounts
Engine mounts are designed to absorb vibrations and keep your engine securely in place. If they’re worn or broken, you’ll feel excessive shaking, especially when the car is stationary.
5. Fuel System Issues
Low fuel pressure, a failing fuel pump, or a clogged fuel filter can disrupt the fuel delivery to your engine. This can cause the engine to run unevenly and vibrate at idle.
6. Exhaust System Problems
Leaks in the exhaust manifold or a clogged catalytic converter can lead to uneven exhaust flow, causing vibrations. These issues can also result in decreased engine performance.
7. Idle Air Control Valve (IAC) Problems
The IAC valve helps regulate your engine’s idle speed. If it’s dirty or malfunctioning, it can cause rough idling and vibrations.
