Quick question from an new and non-mechanically minded member if I may?
I have a T reg 1.8 Zetec focus which is up to date on the service schedule, but which yesterday I noticed was throwing out a fine spatter of unburnt fuel from the exhaust. Drives and sounds fine but am I right in suspecting the Cat might need changing?
Is there anything you guys would advise checking/ doing? Got a reasonable journey planned this week and don't want to aggrivate anything.
Thanks for any help in advance
