Falling asleep while driving.
 

I think my engine is putting out extra Carbon Monoxide. It stinks a little in the cabin as well. The car doesnt smoke or smell funny from the rear, I have factory cats. I do have an exhaust leak though before the cats.

I feel sick. BLAlAAALAAAA

if your leak is before the cats, then you definately are getting exhaust inside the car.

Carry a carbon monoxide detector with you and wait for it to go off.

I did this in traffic one day and it went off!

Atlanta air SUCKS!

Better fix that hole in the Saab:D
HA! jokes

Maybe 'Cause everyone is pulling off their emissions equipment ?:rolleyes:

The rex is very prone to sucking in fumes if there is the slightest leak anywhere in the rear. The leaks can be in the taillights, the rear hatch gasket, to a hole in the body. I have seen numerous rexes with an open hole in the spare tire well. Look at the bottom of the well and see if there is a drain hole. If it is open you will get a large amount of fumes in your car. I think this drain hole originally had some type of rubber valve in it.

One other possible hole is the radio antenna drain hose. If it is missing or out of place there will be a hole in the body there where fumes can enter.
