Zeevert was right about all but one thing. Cylinder two is the rear middle cylinder on a V6 or the second one from the passenger side on a 4 cylinder.

po303 is cylinder 3 misfire, po304 is cylinder 4 misfire, po305 is 5 cylinder misfire. this means it could be bad plugs, wires. or coils that are bad. change plugs and see how it is running.
