Stuttering on moving off,

2011 1.6 Octavia.

 After sitting for a while eating an ice cream , when I moved off there was a small thump/backfire and stutter which cleared and went ok after.

 Just for curiosity  scanned it and got the following :-

I cleared the codes then rescanned and everything was clear.

But when looking at the laptop the engine started hunting when idling as if running out of fuel . revved it up and it did it again , revving up second time it cleared and idled normally .

Rescanned to see what caused that there were no codes showing . 

I  scanned it about a month ago and there were no codes apart from this which has now disappeared.:-
