Cel p2272
2013 GS dry sump headers/cam & tune
Started throwing P2272 today but is running fine. I believe this is rear O2??? But the tuner turned my my rear O2 sensors off
which is what is confusing. Was tuned 2 years ago and is running fine. Tuner has moved out of the country or I'd call him.
I did change my valve covers back to stock last weekend after my chrome ProForm covers sprayed oil all over my engine (crappy fill plug).
Am planning on a road trip this week and won't have time to get the car in to another runner before leaving.
Any harm with taking the 2000 mi trip with CEL P2272?

Well looks to be fixed. Turns out the right rear O2 was unplugged. Plugged it back, couple of erase messages and it's off.
With the rear O2's turned off in the ECM, I wouldn't have thought it could still throw a code????

If you post the tune file, we can check to make sure that the rear O2's where disable in the tune (engine diag/ exhaust table in HP tuner and pretty much the same in EFI live a well).
