Low Rpm missfire - causing it to run rich, then leans out as ECU re-learns

I have had 2 occurances of a low rpm miss (as you pull away in 1st & 2nd), almost feels as if you are dropping 2 cylinder.
This causes the AFR reading to shoot up and causes it to start rocking (stoich) up to 900mv at idle, this normally only reaches 800mv at idle maximum.
If you then give the car a thrash the mixture seems to come back into line and will stay there till the next time it missfires.
Is my Lambda on the way out ?
