Re: Stiff gas pedal
The throttle plates are progressive, with the first maybe 20% opening just the small primary throttle plate. Then you start to open the secondary plates after that, which are much bigger and have a much stiffer spring.
So to some degree that difference is normal, but perhaps the overall force you are feeling isn't. Open the TB by hand and see if it is abnormally stiff, if not, maybe the cable isn't moving freely?

Re: Stiff gas pedal
This sounds too simple, but check to see if the throttle is rubbing against the tranny tunnel. Then check the throttle cables. They should have two clamps securing them to the top of the plenum. Then check the throttle body. You may have to remove the cover to check that the cables are properly connected to the throttle plate cams or rod. It could also be that the throttle plates are binding in the throttle body.

Re: Stiff gas pedal
Have you been hiding your Viagra in the gas tank? I hear that can make the pedal stiff...
 If it stays stiff for more than 4 hours consult a doctor. That's what it says on my package.H

Re: Stiff gas pedal
30 mins with the subject of one of Jeffvette's avitars is the perfect cure for a stiff pedal...
