Take it off, lay it somewhere you can watch it, turn the key to on and see if it moves at all while it's still connected. It should move forward then come back as it calibrates, however, the engine computer may be telling it to bring the idle up for a reason so first check the fault codes by using the key method. On, off, on, off, on and watch the 'engine' light it flashes codes and 5 flashes and 5 flashes means the end of diagnostics. A code 22 is coolant temperature sensor, a 12 is the battery was disconnected. There are many. You mat find something else is wrong causing this. Try taking the battery negative cable off and waiting a few minutes to reset the computer. The idle speed motor is probably bad, but you may find something else, just to be sure.
