Tell me what rpm's your car needs to start and to keep lean burn. I suspect rpm's are the controlling factor and not speed. I might be able to advise you better with that info.
RPMs seem to be best around 2500 @ 75 mph. Higher geared trans = higher speeds. MPG is suffering drastically to all this testing and going 70 to 75 mph all the time. This is making me want to do alot more areo to the car to help my gas mileage at these speeds and help stay in lean burn.

I will try this as well. Some times the coniditions are right for lean burn, but it does not engage. Could be why.

I just put in a fresh O2 sensor and was hoping that would help out. I am not getting the P1164 error code anymore, but not any noticable differences.
