Check your fuel injectors. I've replaced two of mine already and it's a common problem on the 3.3's. You can unplug one at a time and check the resistance which should be around 12ohms. Anything higher could be causing the problem. Check the #6 injector first. The backfiring could be related to a timing problem which is a whole different issue but check the injectors first is what I would do.
