Hello, i was wonder ing if you could point me in the right direction... I have noticed every time i start my vectra 1.9 cdti 150bhp 06 plate is shakes as if parts of the car are going to fall off. It always starts first time, but the car feels it is struggling to start??? I was told this is a common fault but i don`t believe that.. Also getting alot of road noise coming from the car since i swapped some of my tyres over.. I have replaced the front tyres with tyres with a different tread pattern and they look very meaty.. Since then i can hear a noise coming from the front of the car.. I guess this is due to the depth of the tread perhaps???
