Symptom indicates the firing order could be wrong. Which engine do you have and do you have the firing order?
Remove the distributor cap and recheck it for presence of water. Moisture can hide and show up to cause trouble when engine heats up.
The best way to go about is to remove the caps and wire to dry out afer the engine has been running for a short while. The heat from the engine and its components would help to dry out everything.
On the other note, if misfiring can be due to a faulty ignition coil. Weak coils can go back when misfirings occur. Hav it checked as well.
