147 2.0 Lusso shuddering on acceleration
My 2005 2.0 147 Lusso has started shuddering on acceleration, I have had this wonderful car for over 2 years and apart from electrics this is the only worrying issue I have had. This only started 2 days ago but is now quite obvious especially when town driving. Yesterday my engine system control warning also came on for a few minutes.
If I drive with a very light foot everything is ok, also if I push her hard then all feels ok apart from a slight lack of power. It is most pronounced in town. Is this likely to be a fuel issue? new sparks and fuel filter? Or am I looking at something bigger and costlier? She has also had an oil leak for quite some time now and can occasionally smell burnt oil in the cab, she's losing about a litre a month. Any advice would be greatly appreciated. And Hello to all as I am new to the site.
