2002 Hyundai Santa Fe GLS 2.7L MIL Lamp on
Vehcile came in with a miss fire - replaced plugs and wires and misfire went away. Now getting PO1166 - checked all O2 sensors and they are reading correctly, but the same code keeps coming back. The scan tool isn't telling us anything else. Hope you can help.
