Help with code: KOER 1-2

[jokergotcha]

im a diag tech one of the first things i learned about ford tb is no cleaner as of late there are a few special companys that make cleaners for fords but as most know the first time you remove your air tube theres a sticker that says do not clean throttlebody may damage ive actualy had to replace throttlebodys because new techs did fuel sys cleans which isnt a prob if its right for a ford or you dont use throttle plate cleaner
