Update from a recent post but i still need help. The engine keeps cutting out randomly was told it could be the coil pack so changed the coil pack and its seems to have done nothing it seems like the engine hasnt got enough revs to keep it running you can see on the rev counter the engine loosing regaining then loosing revs till eventually theres not enough revs to keep it going and it just cuts out. Anyone know what it could bee roughly how much to repair it aswell would be good

Look to the fuel system, sounds very much like it's starving of petrol.
