Hi,
My car idles absolutely fine once warmed up.
It just idles rubbish whilst warming up.
I have cleaned the idle screw and AFM with carb cleaner.
I am fairly sure the SAD is opening for a while when cold, though it may be closing prematurely ?
1) What is the most likely cause of the problem for poor idling, whilst the car is warming up ?
2) Has anyone ever tried putting a resistor is series with the SAD, to delay it closing ?
