Can you run us through how you did the initial set-up with the hand-held? What are your IAC numbers at idle? Where do you have your Key on source power too? These systems are not as "EZ" as it sounds, so the more info the better.

You should not see 1400rpm's unless you have somehow opened the butterfly's on the throttle body or you have some serious interference with your 12v signal.

I never had an issue with my system.....I installed it myself though, so I confidently know where to go if something is a miss. Sounds to me you need to have whomever installed the system, take another go at it.
