probably just your guage getting messed up. Your o2s have nothing to do with your oil pressure becuase oil pump is mechanically driven and not related to the electrical system.

Unless unplugging the 02s caused the idle to go up which in turn would increase oil pressure reading.

sounds like an electrical gremlin

increasing the idle should not peg out the oil pressure gauge, hell a stock or even a high pressure oil pump shouldn't peg out an oil pressure gauge if it working correctly

Reads like the sensor is not longer plugged in.

Haha I didn't see the pegged part, guess I need to finish reading sentences instead of assuming. I assumed he meant his oil pressure went up.

If our car's PEG the gauge when it's unplugged, then it's possible he unplugged the Oil Pressure sensor and not the O2

Now, it's less likely on 94+, but on our 93's the oil pressure sensor is down on the oil filter adapter housing. Not behind the intake manifold like 94+. Though, after thinking about how that is setup, I don't think it has a long tail like the O2s do, and the sensor plugs right into the pressure sensor, so it would be less than likely anyone would unplug that by accident.

yea i'd say he unplugged the oil pressure sensor also.it will peg the gauge for sure
