Answer 1

That is odd, It is still practically brand new. Did you check your fluids? It is s a very hot summer , maybe one or two of your necessary fluids are extremely low.
Your mechanic should have checked it on your last oil change.
Engine sputters comealso when you mix your gasoline type., even brand name alone can cause some type of problems.

Answer 2

If it does it all the time I don't know what it is. If it does it just some of the time, spontaneously try replacing the HAL effects sensor on the distributor. I had an earlier ford that played up for six months, I replaced this and that and it seemed to come and go, it was driving me insane. Then an auto electrician fixed it in a hour. He said all fords do it eventually. Worth a try.

Answer 3

You may have a sticking EGR valve, could be built up with some carbon and not seating causing a real lean condition at idle.

Answer 4

Because it is a Ford. Kinda of kidding but it is hard to tell with this limited info. Write back and tell all.

Answer 5

you might check to see if you have a built-up sludge in the air intake throat or throttle body-that could cause problems.
