Limp mode help!!!

[dando_172]

Hi guys right this is doin my head in now. U have all prob heard this befor but here goes.
Bought my 172 two weeks ago, now first couple of days running fine and then all of a sudden it jumps into limp mode and engine management light come on to. Took it back for them to sort and they changed centre section apparently that was the problem. But it wasn't couple days later both on again second visit to garage they have cleared all faults and said it should be fine. Well today limp mode on again but no management light so it's going back for a third time. Can anyone shed any light on what might be the problem. Running fine no misfires or anything but Seems to be using hell of a lot of fuel.

Thanks again guys and sorry for the book.
