hi recently purchased a 55 plate 1.2 twinoprt its got a massive flat spot on acceleration so basically i can only use the first 10% of the throttle pedal travel is there a common fault on the throttle body because i have changed it for a second hand one and the fault still persists i have also changed the MAF sensor i have checked the throttle position sensor on a sapon diag and the numbers go up and down correctly with no jumping i am going to look for air leaks on the intake just wanted to know if there is a known fault thanks
