I have the same problem man...
I'll fill up.
Drive 10 miles. Go into a movie. Come back and start my car and im at 3/4 already and I was parked on a completely flat surface.

I took it to the dealer and this is what you need (my stealership ants $252 for this part plus an hour of labor ($100)

Depends on if its the front or rear 02. I havent had to do the front yet, but i can tell from looking at it that its the hardest to replace BY FAR. The rear on Bank 2 is probably the easiest, the only "hard" part would be getting the stock wiresand plug from the 02 to the engine bay...and thats still easy if you use the coat hanger/elect tape method.

Yeah sensor 1's, either bank are far harder than the rears
