Hello, I am sending you some information on resetting the oil life system. As for the way it is running, my first thought is that you should have the system scanned to see if it has any stored trouble codes that may point us in the correct direction, in the event that there is a problem with one of the sensors or something similar. The oil change light should not have this kind of an effect on the truck at all. But you can try driving it after reseting the system to see. Depending on how many miles are on the truck and what has already been done to it, the first things that come to mind are maybe a restricted fuel filter, or even a fuel pump pressure problem. But as I say, without driving it and knowing the history on it as well as the miles, that is just a stab in the dark. Some of the larger auto parts stores like Auto Zone and Pep Boys will scan the system for you at no charge and if that shows anything, then we will have a better idea of what area to look in for a problem. Info below. Thanks
