Winter Quirks

[Vbonz@aol.com]

I have a 1990 200q in mint condition.  When outside air temps are 15F or 
colder, the car makes an annoying howling noise.  The car will howl for about 
2 minutes.  It has always made this sound on cold days and the colder it is 
the louder it is.  It will make this sound at idle and acceleration.  I think 
it may be the turbo.  Any suggestions.  Also my cruise will not hold set 
speed on extremely cold days.  Once the engine warms up it works as normal.
