Default Idle too low?

Idle was fine before, never had any issues with it in the passed week or so that the car has been running..

Disconnected the battery today, changed my fuel filter and fixed a wire on my passenger side O2 sensor. Battery was probably disconnected for about an hour. Reconnected it. Started the car. Idle was a little high at about 1100 in park. Backed the car out of the garage and left it running outside for awhile. I was cleaning up the garage and I heard it choking a bit so I went out to check the gauges. It was idling at about 800-900 in park. Dropped it into gear and the idle dropped to 500-600. The car is shuddering, and when I tried to drive it around the block, it was getting bogged down. How did this happen...?

It was the pink wire on the O2 sensor. Noticed it was cut a couple of weeks ago, and just now got around to fixing it. Not sure how it would make things worse that before.

Try resetting the IAC. With the car off, depress the pedal slightly, then start the engine. Let go of the pedal and run the engine for 5 seconds, then turn off the engine for 10 seconds. Restart the engine and see if your idle has changed.
