Hmmm.. maybe the throttle position sensor? First double check the linkage under the hood and make sure when you push the pedal, all the bits are moving as they should. Then, grab the bentley and pull off the throttle position sensor and measure the resistance values and compare with the bentley.

If that's over your head, read up on it or just take it to a shop, but I'd encourage you to read up.. Its free!
