Stuttering, Losing Power, 12mpg, Wtf?

I think if you unplug the battery, it should clear, if not get someone to plug in a obd and wipe it clean

Yea, unplugging the negative should erase it.

I had the very same problem and replaced my o2's and it helped but didnt go away. Now 10k miles later its getting bad again. I'm cuting my cat out in the next day or two, hope it helps.

Yea, that helps, I'll keep that in mind.

don't forget, your trucks symptoms might betray a vacuum leak some where..might wanna do a rundown of your lines, caps (including gas), etc. Personally I'd do this before the 02 sensors, cuz they can be a pain to get out with the pipe in the truck.

I sprayed carb cleaner all over and didn't find one but when i had the drivers side inner fender off i found a 5/8 rubber fuel line style hose that was ripped completely off its fitting so i found a replacement around the garage and replaced it. Wouldn't it only be a vacuum leak if it were constant stuttering?

not necessarily, vacuum leaks can be pretty iradic at times. My mom's grand am had one that let her drive all over town and then would stall out at a random red light, but then start right up. A friend of mine has an old gmc aerostar that stalled and wouldn't start back up. Its pretty much all over the whole range.
