Question

2002 hyndai santa fe rough idle no power obd error p1166#11

Answer 1

Hi there,

The code is for the front O2 sensor. This will not cause a power issue, however if there is another issue with the vehicle it may cause this code. I would look for a problem with a blocked catalytic converter when you have this code with a lack of power. You may also have a timing belt that jumped time.
