you need a new post cat o2 sensor
or you need a new cat.

Start cheep and put a new o2 sensor in. Yes, they are a hundred bucks but these things do burn up sometimes.

Hope it works out for you, you do have 2 O2 sensors, I'd start with the post cat, and if that dosn't fix it, fix the pre cat and if THAT dosn't do it, you are probably having an issue with your engine or the cat itself is bad.

It dosn't smell like rotten eggs does it?

yep, do the post O2 sensor. Same model number, shouldnt be any different than a pre cat O2 sensor, it's just where it screws into the pipe.

If I were going to replace just 2 02 sensors, I would put them before the cats. Those are the sensors that change the mixture going into the cats. The back sensors just do a double-check to see if everything is okay. If that doesn't work, you probably need new cats.

1995 325I, window tint, K&N, debaffled airbox, BMW #104 wheels, Nighthawk low beams, smoked side markers, smoked corners, smoked taillights, M3 stlye heated mirrors, various interior bits, Bosal cat-back.

yea o2 spoof..they have them for my 99 grand prix, it fits into the o2 spot makes the computer think a real o2 is in its place. a whole lot cheaper than a new o2..my spoof was $25 and a new 02 is 98.99

does the same thing. esp since the rear o2 doesnt set a code considering its not really monitoring the cat.

Yah, a spoof is what you do to a 9 grand prix, not an engineered BMW.
O2 sensors are there for a reason, and there's a reason that if they fail, they throw the check engine light on.
Without the information from these sensors, the fuel\air mixture will be wrong and will result in poor gas mileage and poor proformance.
