Another reason for a sluggish truck is the AFM sensor and or throttle body/position sensor. Had to replace that in my current chev 2500 express. I tried the AFM sensor and that wasn't it so I tried the TP sensor.
The sluggishness was because when that solenoid fails the computer puts the van in “limp” mode. It defaults to 3rd gear so starting off was really slow but once I was up to speed it drove fine.

The repair went fine and I’m good and fixed

Yeah that freaking limp bizkit mode! When my TP sensor went out and I needed to go to jobs the truck would only run 2-30-50 km/hr and it ramped up so slow, I would erase the code and it would become normal again. One morning however the freaking OBD2 scanner started to smoke! F-me and I couldn't erase the code and i was going nowhere fast. I over nighted a new scanner but got my part in first. I installed my sensor in a parking lot and it was really snowing hard. Several construction worker finished their day on a jobsite right beside the lot and walking by me and I hoped no one would recognize me.
