" Taking in consideration first what @stangorang
" as he replaced hardware that would have had a direct affect on the problem if the hardware was faulty. However hardware was not the case. Similar experience from @SteveAZ
, no matter what hardware changes were done the results were still the same.
For me I have 65K miles on my car, and the dealer replaced the injector with the newer ones when I was at 49k miles. It wasnt needed it was just something done I wouldnt have to worry about. My car does not sit, it is driven eveyday mostly highway milage
I have the orignal o2 sensors when I bought the car new. I am not cattless, I am running CP-e Highflow Catts with stock mid-catts. Mid-catts will be removed befor the end of the year. I doubt seriously a faulty o2 sensor is the issue, as my AFRs are perfectly on target
After increasing the scalar in the "cell range" where the concern is being had STFT bank 1 improved but I could not see bank 2. After logging STFT bank 2 that is where the major problem was and a significant gap between the two banks
So I raised the "cell range" of cocern in STFT bank 2 from 1.256-1.240 to 1.296-1.280 and the gap between the two banks was reduced "
