Understanding the Check Engine Light
The check engine light can indicate various issues, from minor problems like a loose gas cap to more significant engine troubles. Ignoring this light could lead to severe consequences, but sometimes, it just needs a reset. Have you ever experienced a moment where you fixed a simple issue, yet the light persists?
