Are you talking about the Electric Throttle Control (ETC), in other words no throttle cable or drive-by-wire, or the Cruise Control? If it is the ETC, you need to get that fixed, It may be a safety recall thing. You don't want the throttle operating unexpectedly.

I have the ETC on my 01 Silverado and love it, in fact I am also using it on my hot rod when I put the LS1 in it.
