Gas pedal problem

I bought a 2013 Tundra with a V6. I love it.......except

The gas pedal seems to have no push back so every time I step on the pedal, the truck just takes off and when I hit bumps, my foot pushes on the pedal and makes it accelerate. When I'm in a bumpy parking lot, all you can hear is vroom, vroom, vroom. I am convinced this is the reason why I am going through more gas than I should because it is constantly opening the valve and letting more fuel through. I purchased a pedal commander, which has somewhat helped with the initial get up and go problem (except when I'm on a hill) but it didn't fix everything.

Is there something I can tighten or replace?

 

Replace pedal assembly. There are a couple threads with part numbers and such.
