I have a 2013 super crew 2000 miles. I passed a car punched it to about 85mph and check engine light came on and the truck shuttered bad when I gave it gas. In babied it for about a mile and the light went off and runs fine. One thing is I only get about 15-16 mpg at 70mph. Any thoughts. Will the computer save the info when the truck did that, so the dealer will know what happened?
