Cleaning ISV - suggestions please
Hello chaps (and chapesses).
I think I need to clean my ISV. The symptoms are that if you take your foot
off the accelerator, the idle speed sometimes drops below 500rpm and then
staggers back to 800; sometimes the engine cuts out completely.
I've seen various people mention cleaning the ISV recently. How is it done
- toothbrush, immersion, dismantling?
What fluid should I use: petrol, turpentine, carb. cleaner, engine cleaner?
1984 Audi 80 quattro
1989 Audi 100 Avant
p.s. I just read an article in a British VW/Audi magazine about a 1984 Coupe
with 300k miles on original engine (10kmiles oil flushes and changes). Car
is still in as-new condition - only major job has been replacement of seat
coverings and associated trim. The running cost have been calculated to be
about 10p per mile (USD0.15)!
