Re: '79 250ci idle speed adjust - truck stalls when coasting

I'll have a go at using terminology from both sides of the pond then - there are quite a few differences!

All vacuum pipes are fine.

I adjusted the throttle stop screw which has sorted the issue. The truck seems to be running rich and is returning around 12 imp. MPG (that's about 10 of your MPG!).

Maybe I should rename this thread with a catchy non Specific title! :P
