80 should be .80 Volts.. that is RICH.. the 16 should be .16 Volts.. that would be lean. These are not good numbers. it will not pass smog.. Both banks should be less than about .1 volt at STABLE Idle 750RPM, with the Ignition at 15 Deg, the TPS set at .45 Volt and the Idle Switch Confirmed as being on. This says to me you have a leaking injector or O-Ring on the Right bank. the left bank is almost lean enough.. that bank might pass..
