i have a saph 4x4 cosworth which has a few bits on it including greens, 3 bar, t35, not sure of the internals of the engine as i bought it as it is. the problem is that it wont idle below about 1600 revs, i have checked for air leaks, i have cleaned the idle speed control valve and still no joy. also when starting the car sometimes it will just not fire until the 3rd attempt of turning the key but then will start instantly. and it isnt very good at running from cold.
any help would be greatly appreciated.
