darren butler Posted June 8, 2014 Share Posted June 8, 2014 Has anyone any problems with a focus over revving ? Quote Link to comment Share on other sites More sharing options...
Invisible Man Posted June 9, 2014 Share Posted June 9, 2014 i had this once the other week, car just stuck at 3000 revs after slowing down, stuck my foot to the floor and it reset.... I believe they have electronic inputs and its nothing mechanical....dodgy sensors perhaps? Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 Did u stick ur foot to the floor while the car was running? Ya I've replaced the throttle control sensor and the sensor under the engine still the same,it's a head scratcher Quote Link to comment Share on other sites More sharing options...
Invisible Man Posted June 9, 2014 Share Posted June 9, 2014 Did u stick ur foot to the floor while the car was running? Ya I've replaced the throttle control sensor and the sensor under the engine still the same,it's a head scratcher I was pulling into a side street off a side street to turn the car round after just setting off. I accelerated quite hard and swung the car in, but the revs stayed up, so I hammered my foot to the floor, whilst the car rolled back slightly of its own momentum, they then dropped quicker than they would do in a normal circumstance. Very strange indeed, first time it has ever happened and it hasn't happened since. Good luck with it mate Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 Might try that because I don't know what to change next except maybe the throttle housing,thanks pal Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 9, 2014 Share Posted June 9, 2014 I think your on the right tracks there, your probably looking at either the throttle position sensor, or the throttle body itself. It could be that the throttle blody is sticking open (due to carbon buildup) so a removal and spit polish wont do it any harm at all.

darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 No I changed the sensor so I'm guessing it's the throttle body itself mate at least I'm hoping so,it sounds ridiculous Quote Link to comment Share on other sites More sharing options...
artscot79 Posted June 9, 2014 Share Posted June 9, 2014 with no info on the car year etc if its an older focus then the idle control valve if newere the guys above have the nail hit Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 It's a 01 1.6 ghia I've heard it's a common problem with them it sounds like an automatic choke not working right,I'm prob totally wrong but that's how it sounds Quote Link to comment Share on other sites More sharing options...
artscot79 Posted June 9, 2014 Share Posted June 9, 2014 on an 0-1 it will be the idle control valve its a common issue if this fails then the car will struggle to drop the revs as it gets stuck easy to change just 3 10mm bolts youll find it near the right hand side of the engine by the battery area disconnect the connector to it and try the car at idle if the revs drop thats youre problem Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 9, 2014 Share Posted June 9, 2014 if its an 01, then thats a MK1.5 Focus I suspect, and that would be the idle control valve. Quote Link to comment Share on other sites More sharing options...

darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 One more question has anybody had any problems with lights going bright then dul both outside and inside the car I know it sounds like the alternator but that was changed and still having the problem Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 9, 2014 Share Posted June 9, 2014 more likely to be the battery. Check that its a silver calcium one, and guestimate its age. If the battery is wearing out, then it will fluctuate on voltage even with the new alternator. Your best bet, is if the battery looks old (definatey if its a lead acid, or any but silver calcium) then you should definately look to get it replaced. Go for something like the Bosch S4 if its compatibile with the battery box size, its a very good battery (been there, had two!) Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 battery seems new enough I only have the car two weeks it's a 01 1.6 ghia the battery came from Halfords but that's all I know about it Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 9, 2014 Share Posted June 9, 2014 yeah, but a clean battery doesnt necessarily mean its a new battery. Also I dont believe that the Halfords batteries are as standard Silver Calcium that they direct Ford owners to. Best bet, get the model number off the battery and post it up, we can check if its silver calcium or otherwise. Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 Cool will do thank you for your help Quote Link to comment Share on other sites More sharing options...
artscot79 Posted June 9, 2014 Share Posted June 9, 2014 dimming when at idle is normal let me guess it gets brighter as you rev? simply put thats perfectly normal on the mk1 no amount of alternators will change that it is worth checking the battery though Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 9, 2014 Author Share Posted June 9, 2014 Ya it's like they flicker between bright and dul when your driving it's really bad at times Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 10, 2014 Author Share Posted June 10, 2014 Can anyone tell me if a battery with model number hb063 is the right one for a focus 1.6 ghia it says it's a standard battery Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 10, 2014 Share Posted June 10, 2014 you can expect a small amount of dimming, but if your noticing it that much (almost disco style) you definatey have an issue Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 10, 2014 Share Posted June 10, 2014 Does that battery have a make on there (Bosch, Halfords, Motorcroft etc?) EDIT: I googled that and it comes up as Halfords, it looks to be a LEAD ACID battery, which as far as I know is not compatible with the Ford Smart Charge system that you probably have in your Focus.. You would need a Silver Calcium battery - you can get these from Euro Car Parts (better supplier I have dealt with). I would suggest, call your local Ford Dealer and speak to the parts team, ask them for your number plate, should you have a silver calcium battery and ask them for their price. They will confirm that its silver calcium you need (I suspect) but dont let them order it, then take the info to Euro Car Parts and buy yourself the right battery.

darren butler Posted June 10, 2014 Author Share Posted June 10, 2014 Ya it's very noticeable in it,but I know where there is a battery from a 05 focus I presume that wud fit and suit my 01 Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 10, 2014 Share Posted June 10, 2014 I think the 05 is slightly larger, but you probably could get away with it! Quote Link to comment Share on other sites More sharing options...
darren butler Posted June 10, 2014 Author Share Posted June 10, 2014 Il see can I get it I only have this car two weeks it's driving me nuts Quote Link to comment Share on other sites More sharing options...
