Suggest you read the first link below in my signature.

Are you sure the engine is running rich or is the term that the deviation is too rich??

Many times the codes are a bit misleading.

Rarely do you actually have a rich code, the are almost always too lean.

What scan tool are you using?

What are the short and long term fuel trims?
