Car That Rocks Back and Forth When Stopped

November 2, 2023

If you have a car that rocks back and forth when stopped, it can be very annoying. In this article, we’ll take a look at the most common causes of this problem and suggest some ways to resolve them.

1. Spark Plugs

The spark plugs in your car are designed to create a spark and ignite the air and fuel in the combustion process. If they are starting to get worn out, it could cause the engine to shake or rock when it is stopped. In this case, you’ll need to replace them with new ones.

2. Bad Misfires

Faulty spark plugs and fuel intake can also cause your car to shake or rock when it is stopped. This is because the motor and transmission internals are the only parts of your car that are still in motion when your car is stopped. If you have a misfire, you’ll need to replace the spark plugs and check for any vacuum leaks or other problems that might be causing it.

3. A Bad Motor Mount

If you have a bad motor mount, your car’s braking and suspension will likely be affected. In most cases, this will be felt as a dive when you hit the brakes and a rocking when you’re stopping. It’s a good idea to have the motor mounts replaced by a professional, as they can be quite expensive and difficult to install yourself.
