one thing you do have to worry about it the butterfly valve for the alt air
sticking.
I was in IMC, temp at freezing, and started losing power, I added power and the
engine picked back up but had my mechanics look at it anyways, they said I
probably had some induction icing and the alt air vavle thats suppose to open
automatically probably stuck.
