What's the code? It will tell you. The rotten egg smell is likely the cat though. What year and code?

Ok code is P0153 this happened before when I fill it up about 60 MI it would go out.
It's a 2006 TJ/LJ bought in 2007 14,000mi.

P0153 (M) 2/1 Sensor Slow Response Oxygen sensor response slower than minimum required switching frequency.

2/1 means bank 2, upstream sensor. So the sensor closest to the rear, closer to the hood.

Surprised it's going bad with such low milage, might want to check for loose wires on it. Maybe clean the connections.
