engine surge

what would cause this? I am getting a surge at idle from 750 rpm to around 1k then back to 750. Nice and steady, very smooth surge.

You may need a tune-up. Could also be the EGR system leaking air or could be a small vacuum leak.

i just did a tune up and I took my TB apart to clean it up. Perhaps I did not tighten it back down? I'll spray when i get home and see if I find any bubbles?
