My MK3 Fiesta suddenly developed a pretty bad vibration issue last night after going round a round about quickly. Under any load now, the car begins vibrating from about 30mph, intensified more by throttle input rather than speed, however if I lift off the throttle it immediately disappears. Would this indicate a drive line fault or something else? Unfortunately I'm over 100 miles from home this week, I've only had chance to check the bottom arms, one rear bush on the N/S/F lower arm has had it so I've ordered a pair of arms, never experienced vibration like this before though with bad arms? Any ideas?
Cheers
