No there was no management light. I have run a diagnostic check on it this morning and there are no fault codes present.
There is no misfire or anthing so I don't think it could be a coil pack. I have thought bout fuel pump on its way out which can be common on these, but the symptoms of that is that they loose power at high revs, which mine isn't.
I've been out in it this morning and it is still fine, so I am stumped to what is wrong with it!
Strange one!
