Thought i would throw this out there to see if anyone else may have encountered this problem. After 15 months in the body shop and all the dust that goes with it, I encountered a few electrical glitches. I corrected 99% of them by removing the ecu and cleaning contacts and plug. However the problem with the oil pressure gauge remains. Gauge seems to operate correctly after warm up. Whenever I hit the gas pedal the gauge dumps to zero then returns to normal as soon as I release it. I have extra gauge cluster to replace it with , but thought I,d ask if anyone had any other ideas before i remove the dash.
