90Q20V CLIMATE CNTRL. DRAG

["Royal,Paul" <royal@bos.msmail.idx.com>]

Hi Folks,
 
 I've got a 1990 90Q20V with an annoying trait.  Whenever I'm running the   
climate control (heat or A/C, but particularly with the A/C) I experience   
very slight, but very annoying drag that is intermittent.  Normally, one   
may experience a slight drag when first turning on the A/C in a car, but   
this goes on and on and on.  The symptom is that you can feel the car   
laboring ever so slightly off and on for the duration of the drive.  This   
can't be normal (can it?).
 Question:  anybody else got this problem?
      if this isn't normal...suggested culprits or remedies
     would be appreciated.

 Thanks in advance,
