whenever i drive now, i dont get a smooth push on my gas pedal...it seems like i feel every bump on the road...i drove my friends wrx and they all have smooth accelerations...but mine just has a rough/rugged feel to it....like im getting a massage on my feet (it sucks and annoying) anyone know what is wrong?

 

its pushing down on the pedal...like it feels like its rubbing against something....all my friends cars are stock so far...and mine is too...i just got mine last week...
