So the computer is showing a cam phase sensor failure Car definately dropped a bank big time. Says bank 1 I did not think i have seen this failure on a 355 posted before Anyway i will keep you guys posted. If anyone else has had this let us know what it sounds like and what happens. Mine sounded like the motor was pumping air. Good oil pressure, good water temp and everything else seems ok. Motor would barely run and i shut it down right away.
