Ford Focus Schlagenhausen Posted December 6, 2012 Share Posted December 6, 2012 hi, i have a ford focus 2001 1.8 petrol and i have been having a few issues with it for a while. To start with i had trouble starting, the engine would turn over but it wouldn't fire. I found that if i hold down the throttle while trying to start it would eventually fire and it would run fine. after a while i had issues where after starting, the engine would only keep running if i held the throttle down. from doing a bit of research i figured this was due to the IAC valve which i replaced (my cousin got me a new gasket and i got the valve from a breakers yard (i cleaned the valve with carb cleaner before i put it on)). this completely solved the starting problem but now when i am coming to a stop and i disengage the clutch the revs drop right down (to like 400 - 500 rpm or something), sometimes the revs just jump back up again and sometimes it just stalls (quite inconvenient when coming up to a roundabout). could this be down to the IAC valve i got being bad? could i have created an air leak? or could it be something unrelated? Thanks for reading Quote Link to comment Share on other sites More sharing options...
shaundonnelly Posted December 6, 2012 Share Posted December 6, 2012 I'm 99% sure the problem u are experiencing is caused by the speed sensor in the gearbox. I had the exact same problem in my 01 1.8 focus when everytime u press the clutch when driving along the speedo drops and the engine stalls and the starts again straight away. Don't think it's an expensive fix and u should def give it ago. Quote Link to comment Share on other sites More sharing options...
Ford Focus Schlagenhausen Posted December 6, 2012 Author Share Posted December 6, 2012 thanks for your reply. with the speed sensor does that cause the speedo to drop out to zero? if so i haven't noticed this (most of the time when coming to a stop i have 1 eye on the road and one on the rev meter so i can reengage the clutch if the revs drop too low to stop stalling) but i will certainly keep an eye on that thanks again Quote Link to comment Share on other sites More sharing options...
shaundonnelly Posted December 6, 2012 Share Posted December 6, 2012 Yea I'm almost sure it did. When mine used to do it I just had to start it again with the key and it drove for a while then done it again. Quote Link to comment Share on other sites More sharing options...
