[Shotimes] A/C woes

[Steve Tatro]

I had that idle whistle for a long time.  For some reason I replaced
my MAF and the whistle was gone.  Go figure.

At least check the MAF screen.  I suppose the right pattern of objects
lodged in the screen could produce a whistling sound.

Regardless, it's not a performance or drivability issue.
