engine problems

Ok here is the deal, have a 99 3.8, flowmaster exhaust, and as far as I know that's it, since I've had the car it has had the check engine light on saying o2 sensors are bad, and vacuum leak large, I have put new o2 sensors in but still getting code, also checked and replaced a few vacuum lines. The engine smells like it is running rich and also idled very strange. Some time at idle it will want to stall and lope below 1k rpm, and sometimes when coming to a stop it will stall, if it isn't doing this it is idling pretty high, about 2k and if I have it in gear, and push in the clutch it will idle upwards and act like its stuck, then finally idle down to about 1.5k and lope there.

Please help because I want to start building it up but won't be able to if I have to take it into a shop!

What codes are coming up? If it's o2 sensors lean, could be vacuum leak. Need to know the codes.
