This is a long term fuel trim code.

If it's on a ME7 car the cause will most likely be a failing MAF.

Could be a possible vac leak.

Could well do, and usually some lack of 'pep'.

The ME7 system is very good at adapting to the MAF failing, so this there may be little or no noticeable difference in performance until it fails completely.
