Glad the cars running good otherwise. What T-Pro version are you running?

I'm running 5.03 (see sig) with Bob's latest bin. That's what I don't understand, why is the ECU ignoring the pro's input at idle when both my O2 sensors are unplugged? When the ECU doesn't ignore the pro's input, the thing idles great (14.7 - 14.9) and sticks there.
