Yup champion coppers here too. Best bang for buck in my opinion.
Disconnect the battery to reset the computer while you do all this.
Clean the throttle body while you are at it. Take it off the truck to do a good job. Non chlor brake cleaner and an old toothbrush. After you are done all that run a good fuel system cleaner and thats about as tuned up as these new motors get!
Assuming all other maintenance has been done ( check level and condition of all fluids, serpentine belt, the usual lol) theres not really too much to repair or replace on these trucks. Aside from tie rod ends and front wheel bearings/hubs (4x4) nothing breaks down on a regular basis
