revving problems

[stoge52]

I replaced the tps sensor (which is what code came up) the check engine light went away but it is still revving very high when it is cold and on the freeway it fluctuates a couple hundred rpms Constantly...also i tried unplugging the tps sensor and starting the truck and everything was like it was supposed to be...

truck is a 2007 3.0l 4x4.
thanks

this is also happening to my truck. rpm is not normal, it also fluctuates. i have a normal fuel efficiency but it still bothers me why my rpm rev higher during start up. already preparing to check replacement parts from Auto Parts warehouse
