CURRENTLY GETTING P0441 AND VEHICLE IS IDLING ROUGH

I've been having evaporative system issues for over a year now. Vehicle idles very roughly and sometimes dies when at a stop. Initially, I was getting P0456 code. I replaced the gas cap and purge control valve (part 53032800-AA). The issue appeared to subside for about a week, and then check engine light, driveability issues returned, and the P0456 code returned. I then had the dealership evaluate, and they replaced the evap harness from the front to the rear canister. Specifically, they replaced parts 5166499-AA (proportional purge solenoid harness), 52102801-AD (canister Purge harness), 52102995-AG (canister to NVLD hose), and 5174236-AA (emissions hose pkg). The issues subsided for about a month, and then code P0441 appeared. The driveability issues started again too. Mildly at first and now the idling is very rough again.

Where do I go from here?

Have you checked all the vacuum lines on the passenger side going back to the charcoal canister?Also the ones under the vechile going to the charcoal canister for being split and leaking?

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.
