hi guys,
can someone tell me how to adjust the idle speed on my fiesta rs turbo and what it should be set to

 

the co adjuster is on the bulk head mate, just 2 the left of the map sensor. if your car is standard co level at your tail pipe should b 1.5% plus or minus 0.25%. hope this helps mate.

 

idle speed on a frst is set on the throttle body with a small screw, discnnect iscv then turn screw with engine warm.

 

the idle speed is controlled by the idle speed controll valve.
funily enough.
this is the most common problem on all efi fords.
take the iscv off and clean it right out with petrol.
use wd40 etc and make sure its all clean and lubricated.
this usually cures it.
if not then ckeck for air leaks on all pipes around the inlet manifold area.
it seems to be more common on cvh engines and i believe its because they are engines that seem to produce loads of oily mess, they always clog up around the inlet manifold area for some reason
