Similar problem here:
I wanted the throttle to be a bit less stiff, so I 're-arranged' the spring pressure by moving one spring attach backwards - sure made the throttle work nicer, but danged if I didn't end up with your symptoms too. Changed it all back to stock, and now it idles like it did before some crazy farm boy decided to make it better....
Also - there is some EPA required hose gizmo that connects to all the throttle bodies - mine was cracked and obviously not doing it's full job. Changed that when I did the clutch along with all hoses and some other stuff. Not an expensive part, but it is well buried under the fuel tank area..I would have expected the fellas who replaced your engine did change that hose, but maybe not?
Good luck - let us know what made the fix for this problem please.
