Misfire! Misfire!

I know there are some other threads on this subject, but I want to know if anyone is having a similar problem. I keep getting a cylinder 7 misfire code P0307. The coil, plug and plug wire are brand new. It takes a fair amount of driving to get it to happen, but it does happen about every third time driving. It must be real suttle because I don't feel it happen. Has anyone had a misfire issue with cylinder 7? I know there was some talk about bent valves and bad injectors, but could it be the cat converter on the drivers side since it is directly downwind from #7?

Take that plug out and see if you cracked it while you were putting it in. I had that problem
