i adjusted the (new)throttle switch per bently,which
from memory is screw it down until it closes, then one
full turn more. i'll double check it though. i have
air and power steering, but only one boost valve, but
i think it is in the right hand corner towards the
front of engine compartment if i know what im talking
about, and i have not checked it, so i'll get after
that once my coffee sinks in, thanks for the ideas. sw
