Replaced the MAF in the wagon after troubleshooting a million other things for random stalling. Me in my infinite knowledge decided that since the previous owner replaced the MAF 6 years ago (with receipts) SURELY that wasn't the issue.

Narrator: "It was the issue."

13.4v at battery terminals when engine is idling with headlights is too low. It should be 13.8-14.2v with headlights,heater blower on(but not max) and radio...at idle.

Did a bit more digging on this and found this thread: https://www.matthewsvolvosite.com/forums/viewtopic.php?t=93366 Looks like there could be a chance that the amp is bad.

Another thing that may be an issue is the electrical part of the ignition switch. The way you descr...

I am having an issue where sometimes coming off the gas, the car will stall, dash lights up like a Christmas tree and then is hard to start. The other key part of this that may be related is that my radio will blow a fuse inst...
