hi can anyone help me.anywhere below 50mph ish i get a lot of vibration throughout the car and i don't have a clue as to what it could be.on a seperate issue every now and then i get a missfire,jerky feeling if driving the car normal and have to accelerate to clear it.sometimes it works sometimes it doesn't.thanks for any advice guys.

Well on first impressions I would say.

 

Vibration through the steering wheel - inbalanced wheels

Through the brake pedal on braking - Warped disks / tension bushes

All over vibration - prop shaft inner bushes

 

Hesitation, jerky mainly between 2k & 3k rpm - O2 sensors (reving over 3k rpm will clear it and it only jerks when the car is warm).
