Hope it's not buggered.
What do your LTFTs look like? After a long drive (canberra to sydney) i got a p0101 (maf volume flow curcuit range/performance) and was getting -19 fuel trims when cruising.
Strangely, a different program read the code as p0172 (fuel trim too rich), which made sense with fuel trims.
I checked my intake (sri) for leaks and unplugged the battery and it eventually disappeared. Don't know if it was bad fuel or just a glitch- cleaned the maf when I got home and has been ok for many months now.
Good luck man
