Unique problem with Fiesta Sign In

Hi, I have a unique problem that keeps occurring. Suddenly while running, the speed-o-meter needle drops to 0 and the mileage is not captured. The car's retardation increases. Sometimes it becomes all right in a short while, but on other occasions, the mile-o-meter displays blanks, and the engine does not respond to the accelerator. I have to go into first gear, and the car moves, but does not respond to the accelerator. After a short while it becomes ok again! Anyone experience this, or knows what the prob might be?

Would be nice to know the year and engine size.

Check engine light on?

Re: Unique problem with Fiesta Sign In

We don't have the vehicle here in the states, so there is no service information available.

If I had to make a guess, power, ground, or communications is being lost to a computer module that is in charge or sending vehicle speed sensor information to the instrument cluster. A good tech should be able to see what is going on as long as the problem can be duplicated.
