My '07 RT---I went to pass a vehicle yesterday and wanted to get around them 'quickly'. I started acccelerating and pegged the throttle. The rpm's began to climb and then the motor started cutting out. I've been able to duplicate the symptom---whack the throttle wide open and watch the tach. When the rpm's get to about 5000 the motor will start missing. Interestingly, if I gradually let the rpm's rise it will not do this--only when I really peg the throttle wide open. Any ideas what's going on??
