  • Ford Model: Escort Estate Finesse 1600

Posted 18 March 2010 - 10:33 AM

Hi Y'all. Recently the idle speed on my ford escort estate (2000, finesse 1.6) has started to stick :unsure: - starts and drives normally, but when stopping the engine remains racing at whatever max setting was achieved by the throttle during the drive :angry: . In this state if you increase engine speed using the pedal it sticks at the new maximum. Usually it will unstick and drop down again after a few minute. Alternatively a quick engine rev can sometimes unstick it- but not always and can just set a higher stick value (as before) :( . It doesn't seem to be a sticking cable or carb throttle link as raising the pedal to pull the cable back doesn't do anything. I have read about an "idle control valve" which can stick but don't know if this model even has one? Alternatively is this an auto choke problem? Any ideas anyone?

More than likely the idle control valve.

Very common problem, take it off, give it a clean, reset the ECU by disconnecting the battery for 30 mins or so and see how she goes then

I am unsure where it is located on the 1.6. On the 1.8 it is under the inlet manifold at the rer of the ngine.

Try looking on wwww.fordescortclub.co.uk as they have covered this issue many times

  • Ford Model: Escort 1998-R 1600 Zetec 90ps

Posted 25 March 2010 - 10:27 AM

i have a 1998/R escort finesse 1.6 16v Zetec and had the same problem. Its only first thing in the morning though when engines cold, My advice is to just let her tick over for about 15minutes to warm up the cold start injectors, thus the engine will run properly then and will not idle funny. Still the Idle Control Valve is located just infront of the coil pack on our engines. its a small Square/ish black thing with 2 wires going into it. Just unplug it and Spray with carb cleaner or something similar. The attatched image shows where it is (RED CIRCLE) ( i also know our engine doesnt have the EFI Unit at the back, instead just the Black Hose that goes straight to the filter box but google images didnt have a pic of ours)

Thats not the idle speed control valve in the picture, its located on the throttle body, remove it and clean, problem probably throttle position sensor tho.
