Need a little assistance on an Issue with my Ride : Cuore 2007 Petrol
i was travelling on motorway and at speed of 90 to 105 KM/h the car vibrates like hell, dashboard, doors and may be engine too.
when i accelerate it a bit from 105 to 135Km/h it goes very smooth, no vibration at all. Wheels alignment and camber work recently done.
so what can be the problem Engine foundation or something else?
