Ok guys i need some help! I have a 2010lnf 52k miles on it! I have a hanh sri on it zzp charge pipe zzp down pipe with cat, and a zzp intercooler! The car was tuned before i got it and so where the mods! I dont know who did the tune! I have had the car a while and it runs fine! I threw the p2237 pumping circuit 02 ! So after searching this web site i decided to swap out the 02 sensor! Got it right from the dealership! I changed the sensor and bought a obd2 scanner and cleared the code! 3 days later the code is back with the new 02 installed! I checked all the wires and connections and they look good! Do you guys think a pcm reflash is my next step? Thanks for any help!

 

Any ideas?

 

I'd do reflash. Could be tune
