You do have a computer on your truck. Your service engine light is eitehr burnt out or missing. You need to get it scanned to see if there is a problem. Also get some choke cleaner and spray around the throttle body to see if the gasket is leaking. ALso check the hose to the map sensor as that can suck together and not let the map sensor work right.
