There are a variety of reasons the check engine light may come on. Unfortunately, this generally requires hooking the car up to a scanning tool to download any potential faulty codes in the computer that may indicate more specifically what may be causing the check engine light to come on. I would recommend having an expert from YourMechanic come to your location to diagnose your symptoms and determine what may be causing the check engine light to come on.
