What would be the approximate cost to fix the timing chain if it has slipped?
on 2007 Pontiac Solstice GXP

Idling horrible. Check engine light came on last night. Had computer hooked up to it twice. One thing is setting off another and another. Guy says either the timing belt has slipped (which he has seen a couple times lately with ecotec engines) or the cam shaft actuator has stuck. Need approximate cost to fix one or the other.

I'd call the dealer or some local garages and compare prices..
