This is the reason why going over your car in between maintenance services is important. While going over electrical/mechanical components I noticed the air pump tilted on its side. One of the rubbermounts & bolts had some how broken off. Luckily the constant vibration didn't tear the hose it was resting its weight on. As you can see in the image, I removed the entire airbox with the maf sensor to gain access. I simply cut a similar size piece of more durable plastic, used a screw with a pressure washer to secure it. A quick fix & avoided future headaches.
