Will a new catalytic converter get rid of that smell or is that also a Jeep thing? Seems like all my buddies Jeeps have had that smell. I'm putting on an all new exhaust from the manifold back... and wondering if I should bother with the cat, no emissions to worry about where I live.
"sickly sweet exhaust smell" Doesn't that usually mean antifreeze in the exhaust?
Do know the smell your talking about... but don't use the cat if you don't have to... creates additional back pressure and heat.

That's how the cops used to describe "pot" smoke, isn't it? Maybe something's going on *inside* the vehicle... ;-)
Simon Juncal did pass the time by typing:
Worst possibility first:
Check your antifreeze level and check it for oil while your there.
You could have a cracked head gasket and be sucking in coolant. Pull each sparkplug and see what it looks like. If all are slightly sooty and one is squeeky clean, that's the cyl that is sucking antifreeze.
You don't say how old it is, new exhaust systems will smell funky till the machining oil burns off and the metal carbons up.
A failing catalytic converter usually smells like rotten eggs
Good idea, it doesn't have any classic signs; very little smoke at start up, none visible while running, no odd temp changes or overheating spikes. I'm definitely keeping an eye on the coolant and oil though. Last I checked the oil and coolant was clean, and the plugs looked fine.
I've smelled this on a lot of jeeps (but not all of them) it's definitely more of the sulfur rotten eggs thing... But it's more like the exhaust just has MORE too it, amplified if that makes sense.
A CNN article yesterday said many hotels have bedbugs, and that a 'sickly sweet' smell will be present in the room. Check your seats!!!!
