Have hard pedal. No brakes to speak off. Dennis Haynes said suspect a
vacuum leak. Have just gone over as best I could the vacuum lines in the
engine compartment. With the engine at idle I hear a very distinct sound
like someone drawing kn a deep breath. That to me is like air being wher it
shouldn't. The noise is in the vicinity of the thermostat housing, but I
can't pinpoint it exactly. Is there any kind of vacuum line or device in
that area that I might be missing? It's fairly loud.
