I had this problem a while back and it had gone away but its come back now . Sometimes (not always or even at regular intervals) when changing down to 2nd coming up to a roundabout or junction the whole engine appears to cut out for a very brief period and then straight back on and running fine. I've not noticed it in any other gear. Everything else works fine. Smooth idle, starts first time, pulls well, does about 25mpg normal 30 on a run. Just wondered it anyone had any ideas.
