Touchy gas pedal

The engine service light is not on. The car runs great, but just to much power for the wife on take off. She will not drive the car because like I said early in my emails, even when you push down on the gas pedal just a little bit, the car takes off like a drag racer. I need to know how to either adjust the gas pedal cable or turn down the power on take off somehow. Do you think that the gas pedal sensor could be no good, is there someway to check it? If so, please let me know. Thank you all so much. The wife and I are seniors on a fixed income, right now we just do not have the money to take the car to a garage.

This is the gas pedal setup on our car listed above.

Hello, to answer your question, the car has always had this problem since the first day we got the car. The car run great, no other problem except for the gas pedal being so touchy. The gas pedal is stiff and a little hard to push down, but once you push down just a little bit on the pedal you take off like a drag racer.

Thank You Ken, we have to take the car in for service next month (June). The car has a extended warranty on it, but it is power train only, because it is a used car. I do not know if the warranty covers the throttle cable but I am going to ask, if it does I will have the car dealership change it. Thank you again for your help. I would give you a 5 STAR Rating if possible for everything you have done to help us.
