You can go to a parts store and sometimes they can read the codes for you. You can use the search function in the upper right and get all sorts of cool info.
We need more information to help you. Today's engines use computer codes to describe their issues. Until we have the codes, we can't help you. So get the codes, look them up and then we can offer more.
Would have been nice at the time but the next day at Auto Zone, No Codes Found.....Creepy...
