Answer
Christy,
Sorry to hear about your troubles. The complexity of these vehicles can certainly be a problem at times. If there are no physical signs of leakage or sweet smell coming from the heater vents,( usually a clue that antifreeze is leaking from the heater core).

I would say a that you may have a crack in one of the heads or a head gasket leaking. If the water is in fact being sucked into a cylinder this may account for the odor from the catalytic converter. You should have the cylinder compression checked and this may indicate if a cylinder is bad. The bad egg smell may go away if you remove the source of contamination.

The less expensive route would be to take the vehicle to an emission center and get the exhaust checked. The catalytic converter my be stopped up because of contamination. If the emissions  are out of speck,  you would want to change the catalytic converter first.

If the temperature stays in range, you will have solved part of the problem.

Good Luck.
