Check Engine Light
Which O2 sensors will trip a P0133 or P0153 code? I have both codes and a CEL also. Can I continue to drive the car until I can replace them? Long tube headers and high flow cats installed also.
Thanks

P0133 - Heated Oxygen Sensor (HO2S) Slow Response Bank 1 Sensor 1
P0153 - Heated Oxygen Sensor (HO2S) Slow Response Bank 2 Sensor 1
These codes indicate you have an issue with both front O2 sensors..
With long-tube headers it is a common requirement to swap out the original front O2's with the part numbers used in the rear (the rears are more sensitive / have a different heater element).
Don't assume the front O2's are "defective" (i.e. spending money on new front sensors is not your best move); more likely they won't work at all in your application.

If you have rear O2's in operation (i.e. not deleted).
No tuning necessary that I am aware of on a rear to front swap.
