Hi i have a vectra 1.6 16v 1996 p reg automatic. it is cutting out at random. 1 day it will be fine and the next it might cut out 2 or 3 times. when it cuts out it starts up again fine. the engine management light does not light up when engine is running and there are no fault codes showing. its really dangerous as when it cut out last time i was turning a corner and powersteering went on me. it runs fine and there is no idle problem as it idles lovely. could it be the cam sensor?? i thought it could be this but am unsure as there is no engine management light on. can anybody help?
