Hey Guys, I need your help. I just bought a 2005 XC90. It's got 196,000 miles on it. More than once this thing has choked out and stalled when at an idle, at stop lights or making turns. Last night it completely died while turning into my neighborhood. After about 100 attemps to restart, it finally did after about 20 min of sitting there and I drove it home. Codes read in the past few months lead to the MAF sensor. I did a thorough cleaning but still having this issue. Where should I start? Has anyone had this problem? In other cars, I've experienced this when an idle air control valve went bad. What part on this car would have the same function?

 

I've had something kind of similar where I would occasionally lose power intermittently. check engine light came on and I got the P0103 for the MAF sensor. Replaced it with no change. Some type of air flow issue seemed to be the culprit, but I could never find a leak. It wasn't until I started getting an engine vibration shortly after that a little research pointed to lower engine mounts. There are two lower engine mounts that I know of that both have vacuum lines plugged into them. Why? I have no clue. but I found that when one of those lower engine mounts breaks down, the worn bushing could also provide air flow issues associated with the vehicle via the vacuum lines. Maybe look there.
