Misfire from water?

99' F-150 5.4 180,000

I went through a bunch of foot deep mud puddles pretty fast the other day. Now at lower rpms in neutral there is a vibration coming from the engine. I'm pretty sure I just got some water in the spark plug hole but I only have a few hours before work tomorrow to get it fixed. I'm going to blow out the spark plug holes with a compressor and put some new dialectric on and if that doesn't work check the cop's. If it's not either of these what should I check next? I don't like riding my motorbike to work in the rain.

You will need to pull the COPs to get the holes completely cleaned out.
