Block behind the gas pedal....
The previous owner had removed the plastic gas pedal stop, which bolts to the floorboard behind the gas pedal, but had given me the piece and about two weeks ago I decided to reinstall it. But, with the block in place, when I floor the pedal the RPM's only go to about 2500. I removed the block yesterday and it now accelerates like normal with the RPMs up close to redline. Is this due to wear and slack in the gas pedal assembly? I figure that since C5's come new with the block in place, the car should be able to fully accelerate with it installed. Has anyone else removed the pedal stop?

I just installed that piece your talking about on an 04 Coupe, and I noticed on my car that the gas pedal doesn't even touch the block when it's fully depressed.
To accelerate the egnine to 2500 RPM should take very little movement of the accelerator pedal, what happens when you lightly apply it?
With the block in place how much movement do you get out of the gas pedal?

Without the block in place, he might've bent the pedal/pedal arm/pedal mount. Therefore the range of motion is not normal. I'd inspect the pedal and it's mount carefully for any bending.
Either that, or it was broken in some other way (bad pedal switch, bad TPS?), which caused him to removed the mount to "fix" it, ghetto-style. Why else would he have removed the block in the first place?

Remember that the C5 throttle is "fly-by-wire", there are three sensors located around the gas pedal that sense the position of the pedal. That data is read by the PCM, and the PCM then sets the actual throttle plate position. One advantage to this set up is that in cases where the PCM wants to throttle back the engine (the EBCM traction control function is requesting a lower throttle setting, for example) it can do so while you can keep the "pedal to the metal" without any resistance.
I'd check and see if you have any DTC's set ... if the sensors for the pedal are bad or having problems you should find a DTC set.

The arm that the pedal is mounted to must be bent.
