HI I have zafira 2002 petrol 1.8 that I bought a while ago. when cold start, the engine revs up and down for half a minute and then settles down. I changed the Air flow meter and it worked ok than last month it started again so i changed the Air flow meter and earthed it as i was told and everything was good all working ok for about a month but now it as started again when the engine is cold as anyone got any ideas what it could be please. Ive got no management light on just revs up and down and cant move for nearly a minute when i put my foot on the accelerator the revs go right down and the engine nearly cuts out. Also just recently when im driving its pulling back a bit

Thank you

First eliminate all vacuum or air leaks in the system. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
