Bevauae ur amf sensor needs cleaned or replace. Coroded wireing harness mb manufactre fault so replacement of harness is nesisary also preventing more problems... Relay fuse shot. Coils or spark plugs may need replaced or cleaned. Filter oil and maintenence maybe required. Also may be a fuel or air blockage.
