Car passed the MoT today, good job as it expired a week ago. They had to take it for a blast to get the emissions to pass though and they said it was misfiring slightly. I've noticed it running lumpy first thing in the morning but once it warms up it's fine.
Mine was similar, got back from afghan mid April, mot expired end of April, tested in June. I was driving it all that time aswel! It could have ended differently, but luckily all is well!
