My daughters punto lost power but kept going on the way to work this morning. The injection warning light flashed on and off regularly. When she got to work she called the breakdown service to look at it. The problem had gone when they arrived. She drove home and all was well. It has just had new ignition coils (not Fiat parts) Any ideas - is it worth replacing all speed sensors as I have had problems with these on both Vauxhall corsa , VW polo:idea:
