My wife's 2001 Escape has 175,000 miles. New plugs & coilpacks. Rough idle.. on 2001 Ford Escape

This has been a great vehicle for us but now it is idling rough in the mornings but is ok after warmed up. She said there was an unusual smell coming from the exhaust during the rough idle. Does this sound like catalytic converter gone bad? If so, how much would it cost to replace??
