Weird O2 readings during datalogging... What would cause the O2B1 to go lean around the same rpm everytime, but the O2B2 stays the same? My injector pulse is showing steady on that same side. This happens in the 5100 to 5600rpm range. As soon as it passes that area it is fine all the way up to 6900rpm. O2B1 would drop to 740 while O2B2 would be at 890 and it will flicker back and forth from low 700's to high 800's till 5600rpm and then go back to normal. It is so bad you can actually feel it at WOT. Any suggestions would help. Rumor is I am having valvefloat and that is what I am seeing..
