Hi
I've just bought a 2005 V50 and its an awesome car just a few niggles I need to sort.
•Around 3000 rpm there is an intermittent misfire that's really bad and no boost. Seems to have cleared with use but it's booked into a garage for diagnostics. Is this a known issue?
•Suspension can be very crashy and under acceleration over rough surfaces it's really not great. Would loosing the low profile tyres resolve this?
