hey guys my 89 iroc runs fine but after 3-5 min driving the check engine light comes on i just replaced the cap, rotor, spark plugs, wires and in the process i broke a very burnt colling fan switch. can the switch cause the light to come on or is it in the other stuff i mentioned thanks

 

why dont u just see why its on =] and its all on the cost of a single paper clip, read here how to scan codes:
