3.free both wires from clips around valve cover
4. take belly pan off
5. undo both sterring rack bolts and move seering rack out of the way
6. remove 02 sensors and reverse steps.
Thanks for the step by step but is there any special tools that you would recommend for the job? Did you use any reverse torx sockets or o2 socket wrench stubby wrench etc. I know i've been asking a lot of questions but I would just like to have everything I need instead of making runs back and forth to the store.
