[200q20v] Spastic oil pressure gauge

[Frank Stadmeyer]

Anybody seen this before?  The oil pressure gauge starts flicking back and 
forth between high and low.  I know the pressure isn't actually moving 
around that fast but where does the problem lie?  The gauge, the sender or 
the instrument cluster?  The instrument cluster circuit board needs 
attention because the speedo does its own little dance but the two are not 
necessarily concurrent.  The oil pressure sender which controls the warning 
on the autocheck display has been replaced in the last year.  The autocheck 
display does not give the low oil pressure warning when the gauge goes spastic.

Suggestions?
