I cleaned the trhottle plate and now it runs at a higher rpm than before. I also replaced the engine collant temperature sensor and this did not help. If I shut the truck off and turn it back on it reves faster.

Scan for codes check fuel pressure. Also check with engine off andsee if throttle is sticking, even if it's a drive by wire. Then clean plare and wher eit godes through tbody to get all the gunk out.
