was wondering if anyone could help, my 2001 focus 1.6 auto has been a fooker to start from cold and i now have an EML and when plugged into a fault reader its saying 'bank 1 too rich', both the o2 sensors seemed to be reading fine although my ISCV and TPS were having a fit trying to keep it running smooth at idle although fine when revved and held at revs, any ideas?

thanx
