Coupe Q Maintenance

[Matt Van Houweling <mattvh@van-wall.com>]

I have  a 1990 Coupe Quattro with about 77,000 miles on it.  I generally 
love the car but am now starting to experience some nagging problems with 
it.  The first invloves a rough idle on start up.  I think this list has 
discussed this topic before, but of course I did not pay enough attention 
at the time.  It seems to run fine after it has warmed up, but on sart up 
the idle RPM fluctuates badly up and down and occasionally even kills the 
engine.  The second problem is an anitlock brake light that comes on 
periodically.  When off the antilocks work fine, but when the light comes 
on the ABS is disabled.  After restarting the engine, the light may or may 
not come on.

If any of you have experienced and solved these problems please lend some 
insight.  Thanks
