Ok thank you for that photo, that I have tried to do but I feel like there is a lot of play in where the fast idle cam sits on the idle screw. I will try to get a video to show what I mean, but it may well be normal. Am I doing this adjustment with the car running? I've been trying to set fast idle with the engine warmed but off and the throttle opened to 20 degrees, setting it onto that 2nd step.
