I am surprised you do not have a check engine light. If Jack's suggestion comes up clean then start looking for a slight vacuum leak especially where throttle body mounts to manifold...

With a propane torch turn the gas on(do not light) point it at the flanges, if you have a leak the propane will be sucked in and your speed should change

Here is a picture of your fuel injection throttle body, try unplugging the electrical connectors clean them and add a bit of dilectric grease to the connections, also does your throttle plate have a screw? Is it possible it has backed out?
