Im recently having problem with my focus mk1 i.6 idles. It dops under 400rpm when stoping or when puting in neutral. It happens when traveling in low speed or if you stop at the red light. Already cleaned the throttle and changed the spurt plugs (motorcraft titanium). The idle control seems to be ok. Does anyone have any idea.

 

You try plugging the idle control valve out?

 

Thanks NoRubNoDub, yes i tried unplug-in it it drop the idle to 0 i think. I checked it and i think it was cleaned? any idea? thanks

 

Sounds like the gearbox speedo sensor to me.try replacing that

 

Thanks alo, i havent heard it before. ill give a try. The dealer here in albania is not very professional.

 

Alo, but i have manual transmission, do i have gear box sensor?

 

Yes you have one. It stops the car cutting out when you dip the clutch. Its at the back of the gearbox with four wire multiplug on it.
Should solve the problem

 

Thank you so much, ill change it and let you know.

 

And also i think it might be this sensor because when i brake with the clutch pedal pressed it doesnt happens. It only happens when i brake and stop in neutral without pressing the clutch. The rpm goes over 1000 and then falls to 400 or somth. Thanks again
