Re: What did you do to your xb today??
Swapped out the plugs in the xB. Had some Bosch Platinums in there that I threw in there when I got the box originally. Iíve been trying to track down this rattling noise (a little bit of squeaking/squealing and some rattling) Iíve had while idling in gear and park. Neutral gets rid of the noise though, so I pulled the e-brake pretty good, popped the hood, put it in drive and gave it some revs at the throttle body. Engine moves more than I think it should so I think the mounts need replacing.
Also adjusted the hood... seems it was rattling a bit too. Car seems to run a little smoother now, gap on the plats were about .040 or so. The NGK V Powers I put in were gapped at about .032.
