anyhow, with hptuners hooked up, it's telling me that my right bank o2 sensor is dumping 90% fuel at idle while the left is at 10%. Apparently, this all happened after my header install. First, what would cause this? Also, what should i be checking?

hmm those are weird numbers, but i guess im more familiar with efi live then hp tuners....

after your header install it looks like either you have a leak near the sensors or a bad sensor themselves...this will cause the trims to be off

Check for exhaust leak on the header and if there are none then replace the O2 sensors.

i had the car scanned today.

the codes are P0133B Heated Oxygen Sensor Slow Response (Bank1)(Sensor1)

and P1133B Heated Oxygen Sensor Insufficient Switching (Bank1)(Sensor1)

Any help with this? I tried searching and just found that people were having trouble with the sensors not getting hot enough, but if that was my case i'd have a problem with both sensors instead of 1.

replace your 02's

Replace both O2 sensors with a set of Bosch 13111. They have the longer wires so there is no need for extensions or splicing.
