check your battery...
your alternator mite be over charging it and it makes the battery emit that smell

if the cat is new the only other thing i can think of is the battery also

usually, if a vehicle is running lean, the exhaust will let out a rotten egg odor.

Most egg smells from correctly functioning cars come from gasoline with too much sulfur in them. The catalytic converter converts the sulfur to sulfur dioxide (rotten eggs), which "somewhat" detoxifies it to the environment.

Try different gasoline.

rotten eggs might be your battery...i have the same problem sometimes...but its when i over rev and the clutch slips

Yeah maybe it is the gas that you pump (Gas Station, Octane), or maybe it's true what they say about Jersey?j/k
