Code 32 and 37

[alia176]

The CEL (check engine light) came on yesterday morning and a noticeable difference in the engine performance. There is a hesitation from starting from a stop, perhaps even a hiccup. Once I'm rolling, she's very smooth. I pulled the code after work and they were 32 and 37. No data from both (left and right) O2 sensors.

Upon a closer look, I saw nothing out of the ordinary. Both O2 sensors are in good shape and the connectors and solid. The wire from the O2 sensors are not torn or broken and are still attached to the OEM clips.

What I did see is that my plastic air box (rear of the intake) may be introducing un-metered air into the intake. I think many of us have this issue, the nipples where hoses attach to the air box, this area tends to crack over time.

O2 sensor codes can be generic and may point to other things. I'd like some feedback from the board as to what else to check.

Have a good weekend.

Thanks.
