hey all
ive got a 2002 1.6 focus with a strange idle problem.
when its cold it idles fine but as soon as it goes to warm the idles dip when coming to a junction but when the clutch is out on idle its hunting from 600 to 1200rpm but put the clutch back in and it levels out after 5 secs

idle control valve looks original but ive taken it off and looks immaculate inside

anyone have any ideas whats causing the problem??

Thanks Muchly
