excellent. Im having a problem with my idle speed being too low @700 rpm and the engine gently rocks at idle but never cuts out always starts stops fine etc. the garage attempted to increase the speed using the idle speed screw but nothing turning it in either direction. They screwed in right in and right out to the point it nearly came out. They have advised to get a replacement throttle body. The ISV is ok as like you said the flap is fully closed and flings back easily. Its just had it MOT a few weeks ago and the emissions were spot on. All the metering head was cleaned and I recently had the injectors overhauled with new seals and the spray pattern was good.
I don't think I have problems with a worn potentiometer etc. Just wondering what your views were regarding throttle adjustment screw? Cheers
The engine is the 3A engine
