How can I clean the starter wire on my 2001 v 40?

 

Could you clarify what you mean by intermittent starting problem? As in, does the car just fail to turn over occasionally, or does it just crank and crank and not start up?

 

Your question is somewhat open ended without a bit more detail about your problem and symptoms.
The link below is to a video guide prepared by a forum member rspi
He is a member in several forums as are many members here.

It deals with starting problems relating to engine cranking issues or battery /power/starter type problems and may be just what you need to sort you out.
