Idle Hanging @ 2000

I got a buddy with a 94 3.8 Mustang (Auto trans.) and his idle's hanging up at 2k, doesn't matter if it's cold or hot. Put it in gear and it jolts the car and hangs at 1k while in gear.

I'm just curious if this is a normal issue, if it's an easy fix, and if the 3.8 is like the 5.0 at all in the matter of Idle control and such.

He had a diagnostics run on it at auto zone and they told him his o2's are dead, and that his Cam Sensor may have gone bad. Now, these don't sound like idle altering issues to me; but I've no experience with 3.8's. Any advice is greatly appreciated.
