I suspect you're right. From recent experience all noticeable changes in idle after the battery's been disconnected - whether it's for ten minutes or three days - occur in the first minute or two. All this ' ECU adjusting to your driving style' is for shiny new cars rather than my old banger.

Which suggests my current sensor's basically a plug that stops the exhaust from blowing

So I understand. I won't leave my car and keys at a testing centre next time, for sure!
