nasty exhaust smell

[nixon]

So for the past 2 weeks my cars been sitting outside because ive been waiting for a part and once i finally started it and brought it into the garage the exhaust smelt horrible.....almost like rotten eggs.


Is this possibly a clogged cat? I dont think any coolant is leaking because the oil is its normal color and exhaust color besides from being black the first 20-30 seconds after starting it was normal as well.

Any ideas? Only think i have replaced recently engine wise was the plugs with the Bosch Platinum 4+
