Thank you so much ECaulk. I just ordered one. Should more than likely have this replaced within the next week. Hopefully this fixes the issue.

CudaJoe - My CMD AFR at idle is 14.69 and under 100% acceleration it is 12.75.
LTFT is pretty dormant at -.7. STFT fluctuates.
I disconnected the Evap hose on the intake, didn't change the STFT at all. Hopefully this O2 sensor will do it.

I'm assuming you capped off the evap port also right?

Yes I did cap off the evap port, Firehawk. To no avail.

Well guys, I think the issue has been solved. I bought the upstream O2 from Amazon and I replaced it. The A/F on my interceptor reads right around 14.5-14.8 now. I cleared the codes about 15 miles ago. I've done a couple pulls since then and it feels completely different. It's a whole new world. I didn't know what I was missing! I think the light has been solved!

Yup he did. To a fellow Wisconsinite even! Haha. I'm loving the car so far. It's a major step up from my LSJ!
