I always add my 2p's worth when this question comes up:
When my 1.6 EU3 K did this on the way to Le Mans '03, in conjunction with the usual starter motor problems, the ECU was never the same again - rough running, even stalling when idling occasionally, down on power at the top end. Tried all sorts of sensor changes to fix (even found that it actually ran better when ANY sensor was removed - ie it was in 'get you home mode'). Finally remedied when I got an Emerald, when looking at the sensor outputs it is clear that there are no problems with any of them, my conclusion was that the ECU itself had been damaged when the fuse blew in France...
