Why Does My Car Shake When Idle?

Experiencing a shaking car while at idle can be unsettling. At Wayside Garage in Seaside, CA, we often encounter this issue, and we understand how important it is to address it quickly. Here, we'll explore some of the most common reasons your car might shake when idle and how our team can help resolve these concerns.

1. Worn Engine Mounts:

Engine mounts are crucial for stabilizing your engine. If these mounts become worn or damaged, the engine may move excessively, resulting in noticeable vibrations when your car is idling.

2. Faulty Spark Plugs or Ignition System:

Spark plugs and the ignition system play a key role in your engine’s performance. Issues like worn-out spark plugs or problems in the ignition system can cause the engine to misfire, leading to irregular power delivery and shaking.

3. Problems with the Air Intake System:

The air intake system ensures that your engine receives the right mix of air and fuel. A blockage or leak in this system, such as a clogged air filter, can disrupt this balance and cause your car to shake when idle.

4. Dirty or Malfunctioning Fuel System Components:

Components like fuel injectors and the fuel pump need to be in good working order to maintain the proper fuel flow to your engine. Any disruption in this flow can lead to inefficient engine performance and shaking at idle.

5. Faulty Idle Control Valve:

The idle control valve manages the engine's idle speed. If this valve is dirty or fails, it might not be able to regulate the engine's idle speed effectively, causing vibrations when the car is not moving.

Ignoring symptoms like shaking while idle can lead to more significant issues down the road. At Wayside Garage, we use advanced diagnostic tools to pinpoint the exact cause of your problem, ensuring we can fix it right the first time.

If your vehicle shakes when it idles, don’t wait for the issue to escalate. Call Wayside Garage at (831)-899-2425 or visit us in Seaside, CA. Let our ASE-certified technicians provide you with a thorough inspection and the necessary repairs to keep your car running smoothly.

ARE MY BRAKES SAFE?

By Stacey Diaz • October 14, 2025

October is more than just pumpkin patches and crisp fall air. For many families in Monterey, it's also the start of darker evenings, wetter roads, and more time on the road. That’s why October is the perfect time to think about one of the most important safety features on your vehicle: your brakes. At Wayside Garage, we participate in the Brakes for Breasts campaign every October. It's not just about brake repair — it’s about raising awareness, supporting breast cancer research, and keeping our community safe on the roads. ________________________________________ What Are the Signs Your Brakes Might Need Attention? Your brakes are your first line of defense in an emergency. If you’re noticing any of these symptoms, it’s time to get your brakes checked: • Squealing or grinding noises • A soft or “spongy” brake pedal • Car pulling to one side when braking • Vibration or shaking when you press the brakes • Increased stopping distance Ignoring these signs can lead to expensive repairs down the road — or worse, a serious accident. We always say: if it feels off, bring it in. ________________________________________ Why Brake Inspections Matter More in Fall With more rain, shorter days, and holiday travel ahead, your brakes are under more stress in the fall. At Wayside Garage, we see an uptick in emergency brake repairs this time of year — many of which could have been avoided with a quick inspection. Our certified technicians will perform a comprehensive brake check, looking at: • Brake pads and rotors • Brake fluid level and condition • Brake lines and hoses • Calipers and hardware And if you’re part of our Wayside Garage Maintenance Plan, your brake inspections are included with your scheduled services.
