AndrzejM: thanks, I'll go over it. Circuitry is not my forte, unfortunately. I was hoping for a ready-made kit or something easy!
Old Tele Man, thanks for the reply, but I know the vacuum gauge measures vacuum and not temperature! Also where it goes. :/ The connection is that warmer intake air leans out a mixture, which means one needs to open the throttle plate up just a hair more under normal operation, which reduces vacuum throughout the vacuum system, by how much I am uncertain. See where I'm coming from now? I wondered if anyone actually knew how much the vacuum was reduced, if such a thing has been measured before. This would help me compensate the readings if they are thrown off a bit.
take care.
