Funky idle

Ok, I have a speed density L98 aluminum head motor in a 1969 Nova. You guys helped me out before and now I have a new issue. I have an Idle issue that occurs intermitintally. The car will bounce between 600 and 100-1200 RPM, with cycles occuring every couple of seconds. This problem will occur and go away during the course of a drive. It does the same thing when it is cold or hot, though the engine wants to and occasionally does stall out. There are no vacuum leaks that I can find. Any help would be most appriciated. Also, what's up, TraviZ?

Non-functional EGR, though it is not blocked off. I will check the TPS.
