Hi,

10 Mpg City.
20 Hwy.

What vacuum line is under the exhaust manifold?

I posted a reply on another thread about listing all the vacuum hoses that cause poor gas milage, poor idle and/or have the possibility of leaving you stranded if they fail:

Idle Control Valve hoses (Critical)
Breather hoses (not critical though contribute to poor idle.)
Manifold to valve cover. (Mostly idle.)

Any others?
