I rememmber reading about 97's having a count movement of 0-90 or something and the 98's were updated to 0-250 which kept them from forgetting/having bigger issues.

Understood, thanks for that. I will try to find the broken piece and take a picture, although no matter how many different search terms I use, I can't find what I'm looking for.

Yeah, I'm thinking that on the 99 I may have cracked the small one that goes around the passenger side of the engine bay, it was still pretty cold (-15/20 C) when we started taking it apart.

Actually are there any of them that absolutely need to be hooked up for normal operations? If it's not needed I'd like to cap it and see if the issue goes away, and then hook it back up and see if it comes back.
