Is this (G28 connector) on the bracket that is bolted to the back of the engine below the throttle cable routing. the bracket carries the plugs/sockets for the 2 sensors, and the lambda connection?

I'm interested in what you are saying about the throttle position switch. My car has a little difficulty idling for a few seconds after starting from warm. Because I used the original air temp sensor, I had to disturb those devices at the front of the induction system. So, maybe I have upset the position.
If anyone has a diagram showing the engine bay, with labels to the individual components, I'd be very interested.
