12 year old nissan micra engine keeps cutting out?

I very much doubt if Kwikfit would know what to go for here....the K11 Micra suffers from throttle body problems big time, together with fuel pump relay problems (inside the fuse box, drivers side) and corrosion inside the fuse boxes under the bonnet in front of the battery. Either of these items could cause the car to cut out, but the throttle body is the main suspect.
