I should have mentioned that I previously discovered the intake manifold was cracked at the IAC housing area, so we've already replaced the IAC valve (part 4861552AC), intake manifold (parts 53013403AE), manifold plug, hex bolt, seal, and throttle bottle to intake gasket (parts 53013403AE, 53032410AB, 6509137AA, 53030952AB, and 53030952AB respectively).
Still we get the p0441 code with rough idling. I guess the next step is a very close inspection of all vacuum lines as saturntech9 mentions.
