Oh boy... closed loop computer issues.

well since ive been running the a/f meter off of the stock wideband o2 sensor somtimes ill notice when its running closed loop, pretty much mid acceleration (part throttle) between 3-4k the car will lean out badly(partially fixed w/safc currently) but im starting to think that since the wideband is unplugged the computer thinks its pig rich (few hundred mV then the computer thinks its lean) but it doesnt throw a code so (i think) it leans out the mixture to try and correct it. Full throttle accel never leans out... stays perfect. Anybody have issues like this?

why did you disconnect the sensor again? all you have to do is tap the wire from the air/fuel gauge to ECU.
this way you don't have to run the big wire all the way to engine bay.

yeah i didnt have the pinout and i was too lazy to pull the seat out so i ran a new wire with another plug i have... no biggie. I didnt want to tap it because then the a/f readings for both are innacurate (not that they were REAL accurate before...) you should run one or the other
