I bought this lens used (along with a bunch of others) and couldn't manage to get anything I felt was a viable image unless I stepped down to at least f5 (and even then it was adequate and nothing more). Assuming there might be something wrong with it (it was used, after all!), I sent it to Nikon service in Melville, NY (they've been great, btw). I received the lens and snapped a couple shots. No change.

To really make sure it isn't my imagination, I set my kit up on my Gitzo LS3540 and snapped these shots. Mirror lockup, IR remote release. I shot these in RAW, but exported them from Lightroom resized JPEG at 2000 pixels for the long edge. No other post-processing. All are at 100 ISO, single point focus.

First is wide open at f1.4 (1/50th)

Is it possible I just need to do some fine focus adjustments with this lens?

Let me know if there's any other info I can give.
