P03XX Series trouble codes are all misfire codes. P0300 is random/multi-cylinder misfire, P0301is misfire cylinder number 1, P0302 is misfire cylinder number 2, and so on. Have you replaced the distributor cap and distributor rotor? You should have when you did the plugs and wires. HTH. -Jim

That's a good suspect. Especially if it gets worse after the engine is fully warmed up. HTH. - Jim
