Assuming it was running OK before replacing the water pump, there should be no connection with how the engine runs. Instead, check for vacuum lines or wires that may have accidently become disconnected or broken in the process of doing the work. If the engine did not run well before replacing the water pump, run a compression check to see whether a head gasket may be blown (common with overheating). Also check for evidence of water in your oil (oil not transparent but milky or foamy), which is another common symptom of a blown headgasket but can also point to a warped or cracked cylinder head - all typical symptoms of damage from prolonged overheating problems.
