I have an 05 GT with a JLC cold air intake & an XCII programer, never any problems....But now my car idles way high when started in the morning and actually jumps forward, even with my foot on the brake and then dies. It starts back up and sometimes continues on ok and sometimes starts the jumping forward again. When it's doing this the A/C also just blows warm air. Can anyone help or tell me what type of repair place I should take it. Dealer won't mess with it.......Thanks
