440 dies at the stop light, 440 with hissing noises

["jsadowski" <jsadowski@xxxxxxx>]

This sounds like a vacuum leak. My 69 had a couple of vacuum leaks & it would stall on occassion. Correcting those leaks cured the problem. If you can pinpoint the area the hissing is coming from, check for broken or disconnected lines. The intermittent hissing sounds like what the parking brake release would do with a bad line or the diaphram in the release mechanism has gone bad. That would be coming from under the dash on the upper drivers side.

Subject: IML: 440 dies at the stop light, 440 with hissing noises

my 440 dies when I stop, why is this?  my 440 also makes a hissing noise
thats NOT continuous.  it 'hisses' about 2 times every second.  this this
'hising' noise only hisses when at lower rpm's,  if i speed up the 440 the
hissing stopes.  why is this?  im suspecting a exaust leak...am i right?
