Sounds like a timing issue. Correct timing adjustment is as follows, Unplug and plug in the TPS 3 times and on the 4th time leave it unplugged. (this puts it into timing mode.) make you adjustment via the CAS. After adjusting then plug the TPS back in and see what happens. If the timing light goes crazy while your doing it you could have and issue where one of the cams jumped a tooth or may have a bad pulley. (the outer ring is slipping on the pulley) Try that and see what happens !
