Hey ken. I have a 1999 vectra, and everything will be fine then all of a sudden i get a check engine light. Took to a shop they "couldn't find anything wrong" then last night when i was driving my timing belt came off, and one of the black pulleys, had broken to shreds. what went wrong? or how to fix?
