Bobby - what combo is the system on? a race car? let me know.
what is it doing - loading up and stalling?

3 quick things
1 - an 02 sensor won't be hot enough to work correctly or read accurately at idle (unless it has a pre-heating element in it - some do, some don't) so tuning a car at idle is trial and error.
2 - your coolant temp is 80 degrees - it could be running rich because it thinks its in warm-up mode - faulty temp sensors can do that too - they are cheap I'd change that as well.
3 - i dont know what your running it on but sometimes the throttle blades need to be opened up and the TPS reposition to read right.
