Hi all,

Have engine issue which stutter or hesitate during the drive. No fault code and car have almost all replaced...
  • new injectors,
  • injector loom,
  • MAF sensor (used second hand),
  • new fuel filter,
  • new tank pump,
  • new ECU (second hand)

I went for drive to better understand what really happing and see from data MAF giving very weird numbers. I unplugged sensor but no change and car running with same problem.
Is it here somebody who understand what really happing, please?

I have this at around 1,500 rpm, as does a mate, and thought it was just the state of tune. Mate had a retune and it disappeared. Perhaps yours is more than just the tuning though.
