We start the new year with a check engine light on the console. We drove about 250 miles for the day today and stopped in El Paso, TX for the night since there is s Freightliner repair facility here. Our CATERPILLER engine kept giving check engine lights with no detailed codes. It didn't want to go over 25-30 MPH a lot of the time. I changed the fuel filters 2 times with no help. We will be at the door of the Freightliner shop when the doors open tomorrow.
