Guest username Posted April 12, 2016 Share Posted April 12, 2016 No guarantees, but i'd *guess* octane adjustment means the little CO adjuster potentiometer screw on the left inner wing next to the EDIS-4 module, common for these to go haywire from what I've read. Wait to have this confirmed/squashed by someone who knows for sure what the code is before spending any money though (I believe the adjuster I mentioned is about 25 quid from ford) Link to comment Share on other sites More sharing options...

iansoutham Posted April 13, 2016 Share Posted April 13, 2016 You could always look at the octane adjustment plug (white 3 pin one) either by the battery or coil pack. Chances are a wire may be shorting out Link to comment Share on other sites More sharing options...
