Hello guys! I'm a new owner and a car fanatic, im 22 years old and i got a problem since a bought the car, the problem happends when i floor it, its doesnt acelerate correctly, its like the power go down and it goes up again, its so weird to explain, so i bought a scanner and i saw that the only weird thing here was the pedal position and the throtlle body, do you know what is the problem or what can i do?
( sorry for the bad english, i move to Miami like 1 year ago, i'm Venezuelan)

Was the Fiesta doing this before you bought it? Have you checked all the Boost hoses specifically the Hotside hose? These can come loose and make the vehicle like a turtle on acceleration.
