Default Re: Trucks sputtering after going on the highway

Got a newer 2004 motor from a wrecked ranger in the truck now. Sometimes the motor runs perfect, and other times it idles like it has a lumpy cam. Off the line it has now power (foot to the floor) till about 3,200 rpm when it launches. Its got new plugs and wires, a new throttle position sensor basically everything. It seems to be slowly getting better, dies anybody think i could be from sitting in the junkyard for so long? Like rusty valves not seating all the way? Sometimes it runs and idles perfect so idk
