I know for a fact poking a hole thru the inner membrane decreases ATP production, but how will it change O2 consumption and the transport of electrons, if at all?

ATP production is driven by the H+ gradient in the intermembrane space. With a hole, the gradient will be weaker resulting in less ATP production as you mentioned. O2 is the final electron acceptor at complex IV and electron transport powers the H+ gradient, so with less ATP production both in turn should also decrease.
I guess I was assuming that the H+ gradient was rate-limiting for ATP synthesis. That is, in an equal snapshot of time less electron transport would occur and less O2 would be consumed even though it wanted to since the H+ gradient is hindered.
@aldol16 Just to clarify, uncoupling as in conceptually? Or biologically?
