My Legacy was running fine and then just stalled. It would keep Starting right back up but immediately stall every time. After some research I suspected it was the MAF Sensor, and per Web data I unplugged the Sensor, I was immediately able to Start and Drive but after ~5 miles it went into Limp Mode (barely able to drive, maybe 5mph) and now a CEL. I obtained MAF Sensor Cleaner and while cleaning I found what appeared to be Mouse Nesting in the intake (how it got in there behind the Filter remains a mystery, I see no holes etc…). Cleaning the MAF Sensor did nothing, car remains in Limp Mode. I obtained a Code Reader and I have three Codes PO102, PO113, and PO2109 - all air intake related so my next move tomorrow morning (the car is currently stranded at a convenience store) is to remove the entire Intake to the Throttle Position Switch and inspect for more Debris. Can anyone recommend any other courses of action at this time?

 

Sorry, more specifically its a 2009 Legacy 2.5i.

i did not see a mouse, but what if the Mouse made it to and possibly past the Throttle? I don’t think so as the Engine starts right up with enthusiasm time and time again but immediately stalls each time after. I don’t want to remove the Intake Manifold as that gets more in depth that want to get in a Parking Lot.

Thoughts?
