What is code 1166 on the ODC computer which states an air and fuel magne
Dear sonata-- I have looked high and low and I can't find a Hyundai trouble code 1166. If I were you I would go to a local garage or parts store and they can hook your car up and check on that number for you. Good luck from Bovan.
My check engine light keeps going on and off with a code 1166. What is this and is it serious? Get back to me asap!!
