Default Misfire? Maybe?

So I can not figure this issue out. While idiling my 02 4.7 sits at 500 rpm (a/c off). So while sitting at my idle it will kind of vibrate and the rpms will drop a little. Not close enough to stall, but the needle will drop a couple lines. I am not throwing any codes and with the a/c on I actually idle around 700 without this issue. I have sense changed out the spark plugs with champion copper plugs and I checked all the coils which seemed to be fine. I do have a new tps sensor and I have taken off the throttle body and cleaned everything. My belt was squealing for awhile so I thought maybe it tied into that, but the new belt is on she's quiet yet still having that issue. What does this sound like to you??
