hey,my 1.6 1998 focus developed a fault during the weekend,as soon as u turn the engine on it revs to bout 3500rpm and stays there,if you try and rev it the revs go up then slowly return to 3500,the manifold is also glowing red hot after bout 2 minutes,could it be my idle control valve as the car runs ok wen your doing anything over 40mph above 3000rpm.
