If replacing or cleaning the 'small' stuff doesn't work and you don't
have a vacuum leak be ready to yank the intake manifold and clean out
the passages ($$$$$$ at a shop if you're not DIY). Also, be VERY careful
working with vacuum lines. Some lines turn brittle and connect to
components that tend to turn brittle over the years and the nipples will
break off (again $$$$ for emissions parts).
