Flat spot on 2010 Ford focus

[cmichtobo]

Hi guys i have a customer who owns a 2010 focus 1-6 petrol
every time you drive it you notice a flat spot when you speed up
There is no codes in memory he claims its been like that since he bought it
Anyone had anything simular
thanks in advance

Looking at your join date, number of posts and downloads

going to be a tricky one to find

can you

1) normally drive see when does it

2) racing start see if same point

3) drive 1/2 mile at solid 30mph then just before speed camera
Flat to floor what happens?

4) drive at 50 mph again just before a speec camera then boot it
To 80mph what happens- same flat spot?

5) can you shake the gas pedal like a poloroid picture for as long
As you can eg 148 miles see if logs a code

6) can you hear pre detanation when flat spot?

sounds like it needs a part changing
