Unhappy 95 impreza L wont pass emissons

ok i have a 95 impreza L 2.2l awd and im having trouble passing emissions here are the reasons i think

im running rich im missfiring (when i slow down bubbles and pops)
and im getting a cel code of P1702

now heres what i have i have stock exhuast mani-stock cats
brand new o2 sensors up and lower
new plugs and wires

heres the mods i have
no a/c
no p/s
just running alt
2.5in cat back (welded directly on to the last cat exit pipe)
my cat back is solid one piece from weld to muffler tip
a buddy of mine swapped the auto trans for a 5spd, him and i were told that the cel P1702 is automatic tranmission circut malfunction, i also asked if i needed to get a manual ecu i was told by two differant ppl that that dosnt matter because for my year they were interchangable so what could be causeing this cel to keep coming on and what do i need to do to fix it

second am i running rich because of my cat back and what do i do to fix the afr so that im not running so rich and i can pass I/M?
does it just need to be tuned

third what could be causeing me to missfire?
new coilpack (keep in mind new wires and plugs not even 100 miles on them yet)

thank you
