Rough Idle especially with AC on

2005 Dodge Grand Caravan 3.8L SXT - Keeps throwing a P2302 ignition coil a secondary circuit and a P0032 Ho2s. It has a rough idle especially with the AC on and will hesitate on a hard acceleration takeoff, but if in neutral it idles pretty smooth. I had a cracked coil pack so figured that was the issue. I have replaced the coil pack, the spark plugs and plug wires, I have also replaced the intake gasket (I was told a leaking intake gasket could cause this) and I have cleaned the IAC and throttle body. I checked the IAC function by unplugging it and seeing if it would crank which it wouldn't until I plugged it back in so I know that the IAC is good. I also checked the wires to the coil pack and the pcm appears to be sending the signal to the pack. I'm not so worried about the P0032 code as I figure it will most likely go away after I can find what is causing the P2302. I wouldn't think I have a bad coil pack as it is brand new and I know the plug wires and plugs are good. I'm at a loss and wits end with this.
