My ford fiesta 1242 W reg has started dramatically losing power, particularly when going up hills When idling it is very juddery and sounds like it's about to stall It's done 80000 miles but I have only had it for a few months- any suggestions as to what to check Thanks

Water in spark plug well from wndscreen washer.
You need to check the spark plugs and ht leads as these are known for going down on fords
