You have more than one Bank 2 sensor - which one are you changing? Being a "fuel" code, it's probably the front sensor. A catalyst code would refer to rear sensor or converter. But, for the "P0175" I've seen this more as strictly being a "fuel" problem - injectors or fuel pressure. You really need to test the fuel system and do a sensor pattern scan.

96 GT's have only 2 sensors, both right below the exhaust manifold flanges.

i doubt there's anything wrong with my fuel supply. when i did the heads, i removed the manifold with the injectors still on them, so i didnt change anything.

but if anything did happen, what should i check to see if i'm getting too much fuel pressure?

The rears aren't F6ZF-9G444AA ? Well that's the ones I saw on a '97...

As for the fuel pressure. 35-40 PSI with "Key On - Engine Off" and 30-45 PSI with engine at idle.
