Terry -
This type of symptom is almost always a result of poorly tuned carbs,
worn out carbs, or leaks in the gaskets around the intake manifold.
Also if your brake booster is starting to wear out, you can get air
and vapors from the booster travelling into the intake manifold as
well, but this is less common.
I would highly suggest you rebuild your carbs, and most improtantly
get teflon bushings for the throttle shafts - this will make your BJ8
idle like a rock. You can get teflon bushings for HD8 carbs fro
British Car Specialists.
Cheers,
Alan
