my 2002 S60 keeps tripping the check engine light. I have had the code pulled twice. Both times it said misfire #4 cyl. I have replaced plugs and wires. Light comes on for a few days, and then goes out for a day then comes on again. Car has 178 k miles on it. New timing belt 10k miles ago. Any ideas whats tripping this light ? - Thanks Steve

Ignition coil, intake manifold leak, injector problem or engine mechanical problem. Driving with a misfire is going to damage your catalytic converter so I wouldn't drive it if the CEL is flashing.
