That's part of the problem, when they hooked up the wrong diagnostic computer to the crossfire apparently it cleared the system and I saw the message on the screen that said it could not communicate with the cars system. The dealer has called back and they still say its the additive they put in for the throttle body that's making the car run rough and kicked on the ce light. Took the car in at 8 they gave me a rental and said a couple of hours, now it supposed to be ready at 3:30.
