My RS seems to have a rather low idle, it did have an air leak but i've sorted that. It seems worse when hot, goes down to about 500rpm instead of 6/700 when cold. Can i adjust this without undoing the good work jamsport did? Or is it to do with hot air and the K&N not being shielded at all?

try the idle speed control valve matey!i had a problem similar with an air leak and i changed that aswell and its fine now!there only about £40 i think from ford!

 

have you tried adjusting the throttle stop?
the big knob under the throttle body, just give it a little turn, that should sort it out for you.

 

Try cleaning out the throttle housing, bet its caked in shit. Then set the throttle stop under the housing

 

I will try the screw tonight, i presume its the one with the spring arround it?

 

Thats the one mate

 

Sweet, i'll looses it off once its up to running temp
