Okay, an update here. I checked my fuel pressure while driving the car up and down the road. It maintained a steady 38-42 psi even while bogging down terribly. It also kept that same fuel pressure while accelerating at full throttle (which the car still does well). I am sure that finally rules out the possibility of fuel pressure problems.
My next try will to be replacing the front o2 sensor with a factory item (as suggested). If anybody has any ideas I am sure listening. This little thing is getting annoying and expensive.
