Clean throttle plate on both sides with choke cleaner and check for a vacuum leak likehoses off, pinched, holes, and intake etc. Scan for codes and check fuel pressure

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.
