I suspect that the sour fruit is on a portion of the tree that has originated as a sucker from below the graft, from the sour-orange root stock, and grown up to dominate the foliar canopy. It may be too mature now to remove, but if this had been discovered earlier, you could have removed the sucker in order to preserve the desired fruiting portion of the tree.

I recommend that you have a professional arborist evaluate the situation and determine if it is practical to remove the sucker growth at this stage.
