What O2's measure the O2 levels, i unpluged the ones on the manifold on both sides do any of the other ones measure O2 or just the Check engine light?

 

first question why did you unplug the sensors. The ones that are in the manifold are the ones that send your rich\lean signal to the computer so it can trim the fuel. The ones after the cats are there to make sure that the cats are working efficiently, they should send a constant voltage to the computer.

 

I just finallylyllyylylyllyly got enought money and sent summit their money order for the longtubes and mufflers, and i wouldnt be able to get o2 bungs for a while and before i did that i unpluged them and it so far now for about a week has been running hard as ever!

 

just buy some 18mm nuts and use them for your o2 bungs

 

I wouldn't get headers without O2 bungs. The front O2 sensors help adjust the air/fuel ratio, without them your car is not going to run great and your gas mileage is going to be bad.
