Check Engine Lights After Cobb Stage 2+ Please Help

[1fan88]

Hi everyone,

I just installed the Cobb Accessport, VRSF 3" Catless Downpipes, Berk full Street Exhaust, AFE Dual Cone Intakes, ER Competition FMIC, ER Charge Pipe with Tial BOV. I'm running 93 octane and just refilled with fresh 93 Shell Octane as well.

These are the codes that I am getting. Anyone know about any of them and what is wrong? I was told by Cobb that Stage 2 automatically deletes the CEL's associated with the catless Downpipes so these are different CEL's.

Please note that all of the factory o2 (4) sensors were installed in the new downpipes.

Here are the codes:

P2CAA Lambda probe heating before catalyst, temperature
P2CA6. Lambda probe heating before catalyst function
P29E1. Mixture Control 2
P2C7F. Lambada Probe after catalytic converter 2, trimming control

Please help, thanks guys!!

it might be that you placed the wrong o2 sensor in the wrong pipe.

You have your O2's installed incorrectly.

Which o2 sensors are the problem? The fronts under the engine bay or the ones close to the.back of the downpipes? Also, can I get at the plugs from up top in the engine bay?

Please help guys.. I have heard that one downpipe correlates to gray plugs, while another is both black wires. Can someone tell me which correlates to what? For instance, which down pipe uses the gray? The passenger side one or closest to the drivers side? Thanks!
