2004 oil pressure gage

My oil pressure gage has started to act up doesn't return to zero with the key off, does move and show pressure but never the same place twice, has even done a full 360 degree, this probably isn't the sender but has there been a recall or service bulletin on the gage or cluster?
BTW did a search but no luck if this has been asked before.

There is no SB or recall that I can find. Check the wiring connections, but since oil pressure is the only one acting up, that's unlikely to be the problem. Contact this guy http://home.comcast.net/~bbengineer He repairs clusters, and will know about yours I'm sure.
