Just bought this car for my 17 yr old daughter. Took for a drive and hammered the gas pedal and went about an 1/8th of a mile full throttle. Let off pedal and car died...Thought that was weird. Went home and in park hit gas pedal to about 4/5k and let off quick and died again. New to turbos...any guesses? car has 147k. One owner and clean other than that. Help please!!
