Default Re: 1991 ZR1 ODB1 Port Location

No luck after replacing the plugs
Did the paper clip diagnostic:

From what I could tell:
31 - Cam Sensor Missing or Too Many Pulses
33 - MAP Sensor Voltage High
44 - Oxygen Sensor (Left Bank Lean)
55 - Fuel Monitor Lean
64 - Right Oxygen Sensor (Right Bank Lean)
66 - ??

Looks like a mess?
