I deleted iStat from my Mac using App Zapper, but the icon in the dock remained and now has a question mark on it. I tried to drag it to the trash but it won't move. Any help will be greatly appreciated.

I tried that too. All it says now is, open, show in finder, and open at login.
If you had the utility "Property List Editor" (part of Apple's Developer package) installed, you could probably use it to edit the file <yourhomefolder>/Library/Preferences/com.apple.doc.plist to eliminate that entry from the "persistent-apps" entry. If you don't, you could drag that file out of its folder, then log out and back in again. The problem with that approach is that you'd have to repopulate your Dock with anything you'd put there manually.
