Most Common Reasons Why Your Check Engine Light is On

It causes more anxiety than watching a good horror movie with the lights out. For some, it may seem like the worst thing that has ever happened to them--aside from realizing you haven't bought one Christmas gift yet and it's Christmas Eve morning.

What is this unnerving event that can send your heart and brain into a panic?

It's none other than the dreaded CHECK ENGINE LIGHT!

But don't worry--we'll be there to hold your hand through the entire process!
