wijcc Posted March 2, 2015 Share Posted March 2, 2015 HI all, i am having some issues with the idle rev on my focus which is a 2001 1.6 manual petrol model.When I am driving and come to a stop I put the car into neutral, the revs jump up to 2000-2100rpm and stay there for about 2 to 3 secs before dropping to about 1000rpm - my feet are off all the pedals. When i am in gear and driving the revs seems to be fine/normal - go into gear the revs are normal.Does anyone know what could be causing this, what do i need to look at?Thanks in advance guys.

dave1987 Posted March 10, 2015 Share Posted March 10, 2015 Could be the air idle control valve needs a clean. I did this on my 1.25 mk5 fiesta and it sorted the problem. Sent from my iPad using Ford OC Quote Link to comment Share on other sites More sharing options...
artscot79 Posted March 10, 2015 Share Posted March 10, 2015 Idle sir control valve 3 ten mm bolts is all that holds it on and a connector if its faulty you'll either get revs sitting way too low or it goes the other way and they rev too high Quote Link to comment Share on other sites More sharing options...

dave1987 Posted March 11, 2015 Share Posted March 11, 2015 +1. When cold and under high electrical load if you de clutched the revs would drop down to 5-600 revs and stutter a bit. Fixed after it was cleaned of all the gunk. Sent from my iPad using Ford OC Quote Link to comment Share on other sites More sharing options...
artscot79 Posted March 11, 2015 Share Posted March 11, 2015 The mk1 also had a software update to solve under idle 1 Quote Link to comment Share on other sites More sharing options...
