oil pressure gauge wigging out
« on: November 26, 2011, 03:47:48 PM »
Has anybody come up with a cure for the factory oil pressure gage that fluctuates(or wigs out when it suppose to be still). Mine has done it for years. Ive changed out the pressure switch behind the intake manifold but that didnt help.

Check the wiring and the gauge/contacts.
