Well because vaccum leaks are uncommon on these mod motors and i had the same problem and i changed my O2 sensor. Anything else i can help you with?

No help needed. I'm not saying that it couldn't be the problem, But a lean code is normally not just a bad 02 sensor. If the sensor itself was going bad there would be a sister code along with it like a slow or inactive sensor.

I am new the the mod motor, but from my understanding and what I've been taught is vacuum leaks are not uncommon for any motor with as many vacuum lines as this one has. A rubber hose in my eyes has a better chance of failing then a zirconia or titanium metal sensor.

Any way good luck with repair. Hopefully it is a quick and easy fix. 1 02 sensor will be cheaper then real diagnostic work to find the problem.

thanks!! Ive been a lurker for a while and decided why not post too lol. keep eye out in 4.6 general section, pics of my car will be up soon.
