might be a job for someone with a distributor machine. Although, I think if 1
had a digital timing light, and a vac pump, it might be possible to get an
idea of how much it changes. I think the hard part might be getting just 6
inches of vac, so a reading could be taken, as I don't really know how much
vacuum is made thru the fitting on the FI port (normally). That 6 inches of
vac doesn't sound like much, and more like having your foot in it. ;-) <BR>
