Well my truck runs great but its cold out and i go to start it and it wont idle by its self. I have to play with the throttle for a few seconds then itll idle. It there some kind of choke or some crap on these engines? Its cold out but it also did this in the summer. Everything else is good except that. Its not a big deal but I cant start and walk away i have to play witht the gas for a little then itll be good. Any help
