Q: Check Engine light

asked by on

The Check Engine light is on.

The Check Engine Light will come on for a number of reasons. Since the light is on, I would start by scanning the computer for codes. The codes will help to isolate the problem. If the light is flashing, then this is most likely caused by a misfire. If the vehicle is driving fine, then it may just be a loose gas cap. The only way to tell for sure is by scanning the computer. If you need to get this done, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your Check Engine Light and determine what fixes are needed.
