When your engine starts to misfire, and you notice a decrease in performance, it’s often a sign that something is amiss. One common issue that can cause this problem is a stripped spark plug hole. This can be a frustrating and costly problem to fix, but with the right guidance, you can repair it yourself and get your engine running smoothly again.
