new o2 sensor still flatlines

[zcoh2gdsm]

if you took a look at my last threat about my log with link i found out my o2 sensor was pretty much dead.

yesterday i put in a new one (bosch 4 wire) and then relogged but i noticed when i first started to log it would fluctuate like normal then went to a solid .02v then .04v and flat lined till is started driving, then it would operate like normal. I dont have a wideband so i dont know if im running rich or lean or what.

any help would be great, i know my ISC position is off but im still taking care of boost leaks and such.

anyone have any idea? my car now throws a p0170 code, read Fuel Trim Bank 1, and mind you it's a new sensor.

any help at all? car is throwing a p0170 fuel trim bank1 code now. does this mean that new o2 sensor i got was bad?

Your 02 sensor is flatlining because your combined fuel trim is so far off. You need to adjust your airflow readings and get that thing tuned.

my fuel trim shouldn't have been touched, engine is all stock except for a 14b, 1g 02 housing, 3" turbo back and an aluminum fuel rail. other than that i haven't touched anything but thank you for the reply, if i hadn't known that i'd have pulled the o2 and tried to get a new one.
