For any operational problems with scan9495, PM GaryDoug who wrote the program. He can help you.
Normal O2 operation has them wildly fluctuating in the signal value. 450mv is the center line, O2 reading should be above and below the 450mv center on a regular basis.
If O2's are sluggish or stay on one reading for long periods, there's a problem.
Also don't think egr should be 100% at low rpm. You can test the egr system with scan9495. It should be one of the actuator tests. What will be tested is the solenoid valve that controls the egr.
And before going out to buy an egr valve, remember that wiring, connectors, or solenoid itself could be causing the code.
If you would download the 95 service manual there's a driveability & emissions section to help you. Manual in sticky threads of 4th gen section. Code 32 starts on page 6E3-A-70 .
