88' Audi 90. Getting C/E light al the timeafter just a few minutes of
travel. Mitchell CDs no help and I don't have the big manual. 5 Cyc/5
speed 234K miles. Seems to have lost it's power too, must drop down a
gear lower on hills then in the past. Otherwise runs fine. Any ideas
where to start? I can fix GMs and Chryslers but new to Audi.
