Extremely Rough Idle Problem

[curly2k3]

ok, i am very confused. there are brand new Bosch O2 sensors because thats what the code read for...i replaced those this spring, then i had a bad injector, that was replaced follwed by a new coil pack and spark plug. after all of this within the past year the car was running amazing for about two weeks, within the last week it has been going thru tranny fluid like mad, and this is just recent, and it is a new tranny thats about two years old. not to mention the smell of oil coming from the motor every once in a while, it is not leaking out and it hasnt been running hot or anything, but recently it has been starting harder and even stalled today while idling. any ideas on what is up with my car now? it figures, i decide to make change in mylife and sell it so now it acts up. i pulled the codes and it is still reading O2 sensors... i never cleared them or anything tho. thanks for your help.
