Ok so last weekend I installed the ppe header/catless downpipe combo plus the team moon duals. The catless test pipe comes with 3 o2 sensor bungs, I installed the o2 sensors and an o2 conditioner on the sensor that would normally be after the cat. After a long period of driving the engine light came on, codes read p0420/p0155....Next day car ran like complete shit! I suspected faulty conditioner since all sensors are in good shape and that particular one was like new. I checked fuses - good, I replaced the conditioner with a new one I got today, lack of power problem is resolved car runs nice but still check engine light, code read p0155 bank 2 sensor 1....what sensor is this?? I then wired the left main sensor into the right main sensor via blue/white wires and car seems to be running pretty good. Engine light came back on tho..?? Any suggestions, I will be re-checking the code in the morning. The exhaust install went smooth, no leaks and sounds awesome, happy with product just dont want the CEL! Any help would be awesome!! Id hate to return this item but its starting to seem not worth the $/time/result.
