KOER Code 12? IAC?
trying to pass smog =( hate it so much. I did a KOEO got pass code 11, CONTINUOUS MEMORY got 31, KOER got code 12.
i know that the 31 has to do with the EGR sensor (correct?)
I googled code 12 even though the book said RPMS at idle are out of range/high. What does that have to do with? is it the IAC? Stupid google said it had to do with the airbags. i dont think so. Any help would be awesome. thank you
