I put plenty of brake cleaner through it, if it was dirty, it wasn't after that.

Pretty much. I turned the AC on and adjusted the throttle plate screw until it idled around 900rpm. I also used the megasquirt idle advance settings, when the TPS signal is low enough it adds timing when idle speed drops and pulls timing when it rises.
