citroen c5- rubbish acceleration

[egor110]

Just got a c5 2.2 diesel but the acceleration is dire using the accelerator.
Joining the motorway with foot on carpet it's stuggling with 60mph, stick the cruise on and it pulls like a train though.
I've noticed there's a lot of play in the accelerator pedal it hangs a lot lower than the clutch/brake, could it be a worn spring not holding pedal in correct position?

Is that a main dealer job or sort of thing local garage would be able to do?

Thanks for the replys.
My first thought was floor mats it was when checking them i noticed the pedal was lower than the others.
I'm not sure if it's got a cable or it's fly by wire, it's a y reg 2.2 hdi c5.
