Clio 182
I may have just either developed a fault, or noticed something that has always been there. Either way, when I floor it in my 182 the gas pedal travels as one would expect it to, however once I reach the end of its travel, if I push a bit harder it feels as if it suddenly lets go and travels an extra half centimeter to the floor. Try it in yours when its off, push down on the pedal with your hand and see if it goes down further with more of a push. So i'm thinking that its either perfectly normal, or something is causing resistance and then letting go with more of a push. The best way that I can describe it is that its as if I floor it but someone has their finger between the pedal and the floor, and if I push a bit harder they quickly slide their finger out and it pops down a bit further.
