Default ERROR CODE 2413... Running Rich i guess!

Hello All,

My 1995 S6 is still having a problem with the error code 2413, meaning that it is running rich! I changed the O2 sensor with a brand new audi one about 200 miles ago, the exhaust smells real bad like rotten eggs cause of the rich fuel mixture, and I have an MTM Stage 1 upgrade! I also have a silicon lower intercooler hose. And it is clamped down 100% of perfect, there is no loss of power! But I keep getting that darn 2413 error code every now and then, and it upsets me, the car seems to be running fine. I only put Amoco 93 octane gas in from the same station, and even tried switching to Shell with their 93 octane. Still the same!!! HELP!!!! Any and all of you guys plz help!!!!
Need to get this resolved before i go to the dealer and plop down 100's of dollars!

Default Hmmmm...

If it is stuck shut right after i reset the codes and turn the car on the code should appear right? but it sometimes takes days, other times just a few hours then i see the codes again.
