So it's bouncing between 1700-2000 rpms at idle...1300 in gear. Vacuum gauge is bouncing between 10-11.
Got in there again and sprayed with carb cleaner and it seems there may be a leak around where the manifold is attached. Worn gasket maybe? Loose bolts? Have to dig into that...

Not yet, but I will and spray it again after and see if there's any change. If not, I'll try replacing the gasket and see how that works.
