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.
