Its not surging, its the EBPV (Exhaust Back Pressure Valve) closing due to the low oil temp and the air temp is low.
If you leave it running after about a minute it should idle up and then the EBPV will close, making a hissss sound. Same thing happens when your driving.
About the only way to stop it is to let the truck warm up fully. You can also unplug the EBPV under the turbo, but that is not the correct way to do it.

I also have any early 99 and I have never had or heard of an early 99 surging. I think that your problem is also ebpv related like joe said. I usually never drive mine when its cold I usually let it run but this is the first winter Ive had the truck. When mine high idles and I touch the brake it quits high idling. Not sure about that opening the ebpv back up though cause mine is on a switch anyway. I didnt think it closed the ebpv while driving cause I though I read something about it hurting the lifters not exactly sure.
