given that it cuts out when cold, it could be a temp sensor problem
yeah i was looking on google other day and came across it could be that also. grandad is gonna wait and see if he is asked to repair anything else. as she put it into the garage to see why it was cutting out and they told her it was the lamba sensor which was replaced yesterday but didn't solve problem they also said her clutch was slipping but there is nothing wrong with it. there is a few things it can be so will need to figure out which one.
