Thanks guys. Car will be going to tuner soon, but thats a few days away at least. Today the car started out as i mentioned, i had to drive around carefully, when approaching traffic lights i put it into neutral, lightly touched the accelerator (very gently) which made the car idle nicely, and left foot braked...

Thing is randomly (i am thankful that it happens at least!) if the car starts well the first time then it is able to hold a good idle speed, and at the moment its doing that so i can drive it around normally. the intermittent nature of the situation is a little confusing, you'd think if the butterfly position at idle is a problem (i.e. fully closed) then it would be a consistent problem until resolved?
