Yesterday i was making my way back home had the cruise on and noticed my engine was overly loud and didn't sound like its usually smooth self. i finally came to a stop sign went to take off and the engine really sounded like it was working hard but the rpms werent any different than usual. I was pressing down on the gas and the truck was barely going then all of a sudden the truck kicks in a takes off. Anyone had this or know whats going on i have to make a trip to wyoming wednesday i need help please.
