thanks one garage told me best was covers and gaskets car new to me but has 140000 miles on a 2000 w apart from slight miss that i hope is down to oil leak
changed oil today when i removed undertray i found a wire hanging down re connected it and bingo fault light has gone off this was on intake so hope problem solved have done 200 miles car runs great hope any future problems are so cheap to fix. just got noise from i think rear brakes to deal with now
