I have been driving this set up for a year with no issues and all of the sudden getting these codes. i have oem ntk o2 sensors,no cats and long tubes. do i have bad o2's?.Not sure if it would help but i have a idle log i will post. i have checked for vac and exhaust leaks but none found, if anyone could help out id appreciate it.

Because you have LTH the O2 now get the signal long after the ECU expect it, so you have to tune that (look for O2 response time table) add over all 25-50%
