My maf died with a low input code as well. Mine was intermittant though and it never made it not run. Mine would randomly start reading 0hz while driving and immediately set a cel and the pcm would just switch to my crappy (but correctly tuned) map table. Went to the junkyard and the lady told me 5$ for the one i pulled.... I pulled another 4 while I was there once she told me that. She looked a little lost like her hubby had gone on lunch and left her there.
