Reasons For Car Sounds Like A Lawn Mower When Idling
There are several reasons why a car may sound like a lawn mower when idling, including issues with the exhaust system, spark plug misfires, and other potential causes.
One possible reason for this sound is exhaust system issues. If there is a leak in the exhaust system, it can create a “lawn mower” type sound and release carbon monoxide into the cabin of the vehicle. This can negatively impact your health and well-being, so it’s important not to ignore this issue.
Another potential cause for the lawn mower sound is spark plug misfires. When a spark plug is faulty, it can cause a cylinder to perform a controlled explosion incorrectly, resulting in a misfire. This misfire can produce a sound similar to a lawn mower.
Aside from these two common causes, there may be other potential factors contributing to the lawn mower sound when a car is idling. It is best to have a professional mechanic inspect your vehicle to diagnose and address the specific issue.
