I have a 2006 S80 2.5T FWD. (93K miles) It just started yesterday having problems while idling. The engine shakes, there’s a low rumbling noise and sometimes the engine will have low power on acceleration. I’ve heard it might be the ETM, the Mass Air Flow Sensor or the Idle Air Control Valve, but I’m unable to know for sure. I did a OBD check when the light came on and got P0507, P0101, P0300, P0302, P0304, and P0305. Any ideas??

I just bought this used less than 3 months ago and have an extended powertrain warranty, but don't think it's a powertrain issue, unfortunately!! Please help!

I would start by cleaning the MAF which located inline by the air filter box. There is special cleaner sold in spray can form. While there, look for a vacuum leak from any of the hoses near the throttle.

great, thanks! I'll give that a try.
