88 80: Lumpy idle when hot
Here's one I can't figure out myself: my (carb'd/cat) 1988 80 1.8S idles
beautifully when cold, almost inaudible and silky-smooth at 400-500rpm.
When things get hotter however, idle goes to 1100-1200rpm and becomes
rather lumpy, to the point where the whole car is shaking sometimes.
It's been tuned a few times, all hoses have been checked/replaced. Being a
non-injected car, does this have an ISV? Can't find anything in the Book...

Half a bee, philosophically, must ipso facto half not be. But can it be
an entire bee, if half the bee is not a bee, due to some ancient injury?
