Gordo, you said:
<The reason for one of these that is circulating is that fuel flow was restricted to the No2 engine as one of the liners had moved and was stopping fuel getting to the feed lines.>
Don't know where you got that explanation from, but it's very implausible. The liners can't move at all. Lots of brackets and stuff.
A better explanation might be that the engine may have had it's intake airflow disrupted by, possibly, a malfunctioning ramp.
