Re: Climate Control Drag

 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,

This is the result, IMHO, of the combination of a low displacement engine with a
little flywheel and modest reflected vehicle inertia, and the usual running 
condition of not too much horsepower actually needed for driving.  Whenever the 
a/c cycles on, the horsepower change is relatively significant.  In a 7 liter 
196X Caddie, you might not detect it.  My 1980 and 1984 Sciroccos had really 
noticeable drag.  My 1988 90Q 10V with manual a/c has just noticeable drag.

Add a drag racing flywheel and 1000 lbs to your car and the effect will be less 
:-)
