If i am tracking down a problem and want to check the O2 sensors what would happen if i unplugged them?

 

you will get a light ofr that side O2 fail, and your car wont go into closed loop.

I think your best bet would be to state the problem you are having and I am sure someone here can help you out. If you take them out you will be running in open loop. I drove around with bad sensors the other day (might as well not have been there) and trust me, it wont behave very well.
