This van has a dash-mounted manufold vacuum guage for detecting a dirty air filter. It reads from 5 Inches of H2O to 30 Inches of H2O where the 25 Inch mark indicates a dirty filter.
I just put in a new Fram air filter (Not very good) because the guage was reaching 20 Inches.
With the new filter, it still reaches 20 Inches suggesting that there's some sort of restriction.
Any idea how significant this problem is? Where should I look for a restriction? What's inside the air intake muffler?
