LOL... you're asking the right guy, for while i had that problem, tryed alot of different things, but ill just answer your question
1. No 02 sensors plugged in at all.....
Rich, extremely rich, itll idle as if it has a .750 lift cam until warm, then sounds very mean and deep, drives okay, wouldn't recommend it, might bend a rod
2. Only fronts plugged in...
Terrible, sounded like it wasn't running on all cylinders. In the past my friend has taken off a spark plug wire and i drive ot for 2-3 blocks, sounded simular, just worse, as if it was only on 6 cylinders
3. Only fronts plugged in- before resetting computer...
Scary, wouldn't even drive it, i sounded sad... lol
4. Fronts and simms plugged in- before resetting comp.
Ran okay, not 100%, but an easy fix that anyone could diagnosis
5. Fronts and simms- first couple miles
ran as if only front 02s were plugged in, sounded changed every now and then
6. Fronts and simms plugged in- after 50 miles
Sounds weak, maybe running lean? awaiting tune, not full power, but seems to be fine, after start up it doesn't always run good, after about 1/2 a mile RPMs jump for a second and runs fine again

Any other questions just ask

i have no rear 02s and i have several codes going for my front 02s which seem to be failing. The car is running fine but I wonder if it is hurting my performance at all.

Just did a Dynatech LT header install, no codes, no issues, since the kit comes with cats, I bought vette o2 sensors for the upstream and reused my stocker for the down, they will eventually shut off.
