Inside the car direct center by the firewall. Pull the carpet back on both sides you'll see it, held in by two 10mm bolts.

I would assume that it is in the same location as the 1988 - 1991 Camry, which is under the dash in the middle section.

Here are some instructions from a Toyota forum on how to get to it:

Hope this helps.

EDIT: Confirmed by Lexus2000's post.

Well, because of the weird things the car is doing that would have pointed to a tune up or o2 sensor but everything has been replaced which leads me to believe that the computer might be going out.
