The car will start fine , but if it is not revved it will try andcut out but when revving it is sluggish and splutters . The airfilter is fine . It has been fine after about 5 or 10 minutes but today it started losing power when accelerator pressed at a speed of 60mph.
Any ideas would be grateful.
Thanks Sue

When was the last tune up? And fuel filter change ? How many miles on the car ?

Not sure when last tune up or fuel filter change there is 60,000 miles on the car.

. Replace spark plugs with the exact ones that came in the car.

. Replace fuel filter.
