Sensors and fuel issue

[sazukasteve]

my check engine light is coming on consistantly. I'm receiving a p0170 error code every time. I have old injectors on my 4g63 rebuild and i think I'm blowing my oxygen sensors from ethanol based fuel. I need to pass emissions soon and I'd love to not fix it with my obd2 scanner... can anyone point me in the right direction? I've been searching this site for a few days with no clear info.

Thank you

Just a quick update:
My o2 sensors are new and the intake system is aftermarket and new as well. The only old parts are the injectors. I don't have a tuning device and my pocket scanner is still new to me so I'm working on getting measurements and trying to check gauges. if I clear the error it takes about a week for it to come back on and that's mostly after freeway driving.
