Thanks for the replies so far. I'll hopefully get into it a bit more tomorrow or the next day.

Hello I recently acquired a 2006 XC90 with a 4.4L V8 AWD. Around 155k. The car drives great and had no issues the first several hundred miles. Then one day (a few days after some rain) it was a bit hard to start (after driving 20-30 miles) and started and died. Fired back up with no issues. No check...
