[DML] oil pressure gauge fluctuations

[Soma576@xxxxxxx]

List,

Just in the last two days my oil pressure gauge has been doing strange 
things.  I have the new updated sending unit and normally my oil pressure is at 40 
or so at idle, and goes up to 80 when accelerating.  it has been fine since i 
bought the new sender 3 years ago.  now when the car is at idle, the gauge is 
at around 75 and when i am under load it goes up off the scale but not quite 
straight up and down.  i tried removing the wire from the sending unit and 
observed it point straight up, and when i reconnect the wire it goes down to around 
80.  so, i know it's not totally dead.

last night it started doing this, then this morning it was fine until i 
reached operating temperature, then it started acting crazy again.

what's up?
Andy
