Surging idle

When my truck is idling, it surges between 670 and 700 rpm. It only does it after it warms up good. It just started doing this the past couple of months.

My truck did the same thing, this sounds kind of crazy but it turned out to be the serpentine belt. I was sceptical, but a new belt solved the problem. This is a cheap fix anyway if that's it! Good luck!

I changed the oil and fuel filter a couple weeks ago. I scanned for codes, and there werent any. It didnt do it with the edge evolution, but when I switched to a DP tuner that is when I started noticing it.

Call me crazy, but I deal with CAT C9s and C-9s quite often and they have a very similiar fuel system. And 9 times out of 10 when they surge its because they are lacking fuel pressure... They still run fine, just under a load or sometimes idling they will surge between 650 and 750 rpm.
