Vehicle Explorer can read & store real-time values from over 100 different data items. For example, in your case, you could read the 02S11, 02S12, 02S21, and O2S22 (upstream and downstream oxygen sensor input voltages) values.
I usually like to take the values and plot them in MS Excel. If you did this with the O2 values above, you should get a line in the shape of a sine wave (it should go up and down smoothly) if the system is working correctly.
In your case, you could also check other values, such as the EGR system, fuel pump system, etc., to make sure that they are not contributing to the problem.
Hope this helps.
