Hi there, my mondeo has a problem when idling also when i take my foot off accelator revs dont go down straight away. on startup revs go straight to 2k revs and stay there for 3-4 seconds it idles just over 1k revs where as before it was just under 1k revs im semi skiiled with a good working knwoledge of cars i picked up on the problem a day before it put engine light on as i have good instinct with cars. already tried clening idle control valve with carb cleaner / replacement idle control valve (scrapyard) initially when i unplugged idle control valve the problem went away tried replacement but i cant guarantee it was in good working order got quote of £85 too read fault and £108 for brand new idle control valve. any input would be appreciated as i dont have that kind of money for what should be an easy fix. many thanks.
