    Yours must be missing at idle, mine does the same and also displays code 13. I'm going to have it looked at when it's next serviced.

    It doesn't miss when in Drive or Reverse, yours too?

    How hard was it to replace the oxygen sensor?

    Lucky you. Mind you the series 2 Buick engine was a bit more refined than the early series 1 that was dropped in the early VN's. Christ, I've got one of the first S1 VN's and that thing's a bitch at idle, always has been.

    Default Ok guys thanks for your thoughts.

    Heads have been changed. I noticed when i am in gear say reverse it will stall cause the rev hunts. Still pop and trust me i have changed every sensor there it. I changed the o2 sensor easy as. All u need is a 1/2 inch drive 7/8 Deep reach socket and jobs done. I know they dont idle good at the best of times but its shitting me and im sure they never come out like that, any other ideas would be great thanks guys.
