O2 sensor bypass problems...

I used the diagram from here: http://www.vfaq.com/mods/O2bypass.html
I followed it exactly, I had my electronics professor look at it, and he said it was done right.

Any suggestions? The ceramic resister is getting exreamly hot, thats about it.

Here is a pic of my actuall circuit:
