Ive been trying to pin point when it happens but it does it at anytime, the first couple of times was when it was cold but now its whenever it feels like, also on the first couple of times it was at low speed but since then it has done it on the freeway, hav'nt noticed any pot holes and on the weekend was the first time it ever did it when starting, normally its always happened whilst the car is moving.
Its an odd one, i know its going to be something simple but where the hell do i start.
Actually one thing i found out on the weekend is that the ecu has no bracket holding it in, maybe there is an earth issue there.
