Please help P0303 CEL

I have a 2002 C320 wagon with 60,000 miles on it. The CEL came on and the car is idling and driving rough. I took it to autozone and had it checked and the code was P0303 cylinder #3 misfire. I did a search on the forum but nobody seemed to have the P0303 code alone. Any help would be appreciated before I take it to the dealer will be greatly appreciated

Pull the spark plug and take a look at it. The last time I got a misfire on a single cylinder was at about 60K and it was time to replace the plugs. Did the wires at the same time. I am assuming you have not changed the plugs and wires before.
