Interesting thing happened today. CEL popped on... bank 2 sensor 1 no activity (think I've figured out my surging at low RPMs). I don't know why it didn't kick on sooner; car was left running for a while without it coming on... of course I smelled fuel (not nearly as bad as the other days) but I figured it was just residual burning of old fuel in the exhaust.

Fun little LT1 fact that I never knew. Even though I had replaced that sensor, I did it on the cheap through my Napa Commercial account and they don't carry ACDelco O2 sensors. With the key forward and the motor off the resistance is 9mv. I chased the wires on that side to ensure nothing was broken. Seems a lot of newer vehicles had a resistance reading in that ballpark but this O2 sensor must not be LT1 compatible or defective.

I have true plug and play O2 extensions coming on the 18th (instead of having them spliced since it makes me uncomfortable since it already caused an issue once). Tomorrow I'll switch the sensors around and my issue will most likely switch banks.


...fingers crossed that I am in the clear now! Wanna start saving for a 12 bolt instead of throwing money at stupid things on this car [insert LT1 optispark joke here].
