Rough Idle (with video)

So I just got done installing a high idle switch in my truck, fired it up to test it and noticed the idle acting strange, almost surging. This was with the high idle engaged and the engine idling around 850RPM. In the begging of the video I turned the high idle off and the surging sound goes away. I'm not sure if this is normal, or if I have an issue starting to show itself?

Also, at the end of the video I walk up to engine bay, are everybody else's engines this clattery? I've got 230K on the truck and about 10K on a set of new injectors from LDS.
