You can also use `propane enrichment` if you don`t have a
stethescope. As the engine idles, play a stream of propane
from an unlit torch around mating surfaces and vacuum
lines/fittings. Listen for a change in idle.

Oh yeah, keep the smokers away from the unlit torch--rough on

hey -i had the same problem with a 1986 vette l98 it sounds like you need a
valve job or the val;ve springs are weak or collapsed also check the back of
the plentum for a vacum line that goes to the heater control valve for leaks
also the cruise control system
