    Default o2 sensor extension mess with afr reading?

    Hey guys trying to fix a o2 reading problem reading full lean. I was going to add those o2 extension to pull sensors out of pipe some. The problem is frist it went full lean when getting on plane then would come back after I got on her for alittle bit. But all ways worked at idle. So bought a new o2 sensor did a free air test and still no good. So have new gage coming too. I did add cmi mufflers could they be forcing water back up my pipe to sensor. I have cmi big tube,added bung about 2" after collector and at 12 o clock. Ty Skydog. P.s. u think pulling o2 out of pipe some will give a different reading?

    I think I would try it without the mufflers and see if it goes back to normal.
