First, I'd have the trouble codes checked. Some of the national brand autostores used to check codes for free.

That has to do with your throttle control. A perceived difference between the throttle blade angle and the actual angle. I'd try cleaning the throttle bore. There is a throttle position sensor under the throttle pedal, I can't tell you that sensor is faulty? I'd probably have to use a scanner on it, that shows live engine data.
