'82 diagostic code help

OK, I'm a newbee to this and just pulled some diagnostic codes from my non-modified '82. Hoping I can get some help understanding what some of this means. I had an o2 sensor reading of 475, TPS Sensor .57, exhaust 02 = Lean, with an Open Loop, Map reading of 2.10. All measurements were taken at idle speed. Any translation would be appreciated! thx:

hello, glad you found the "sticky", alot of good info there, but not the info for the values you are seeking. That info would or should be contained in the 1982 Corvette Shop Manual, which is reference to in the "BOOK SECTION of the "sticky", unless someone else has access to such info, and can post here for you. I have never looked up that info, even though my 82 runs just fine, but that is not to say it would not be good info to know.
Another member has recommended using another ECM that would read and datalog much more info that what our stock ECM's do. When I get time, I will add that info to the "sticky" which would be good for any 82 owners thinking about going further with the data in the CFI. Good luck!!!

also thanking bpassmore & terry82 for the reference to the "sticky" ...............Tom

Hey Butch, I hear you.....

We just keep learning from all of the info that we acquire and the actual experiences we go through, makes understanding the CFI easier and easier everyday......
