Default Re: Common Problems with the AU??

Hi all I have a 2000 au series 2 Fairmont
I’ve been having this issue for a while now where it will stutter with anything over 50% throttle. Orgininally I cleaned the o2 sensor with some contact cleaner and it cleared..but it came back so I replaced with a genuine Bosch o2 sensor thinking that was the issue but after 2 days it has come back again…does anyone have any clue what this could be

The next things I’m going to check are fuel pressure reg and coil pack as when I replaced the old o2 sensor it was as black as the ace of spades

In the last 1500kms it has had brand new fuel pump ,fuel filter, leads and plugs.

Thankyou
