O ok. Awhile ago installed my headers, i have finally decided to try and concur my CEL light problem.

The codes i have are:

P0051 sen bank 2 sen 1
P0037 sen bank 1 sen 2
P0057 sen bank 2 sen 2
P0031 sen bank 1 sen 1

(also P0021)

My Plan was to replace the 2 Primary o2 sensors with new ones, and put the dual o2 sim on the secondary o2 sensors. But after doing a little of searching im feeling like maybe this wont take care of my CEL. Any help would be appreciated.

 

my 02 sensor is out as well and it idk if this would effect this at all but my rpms are real hesitant and sluggish would the 02 sensor have anyhting to do this?

 

Why are your primary sensors bad? Were they before instal? If not they shouldn't be bad.

Your options are o2 sim.

Or o2 sim+ resistors. That way you can take off the 2 secondary sensors rather than tucking them under engine bay.
