1992 Cadillac Brougham fuel / ignition management
In reference to previous inquirey: can I send a picture of this thing and you tell me what it is and does ? I capped off the vacum port (hose is fine, no leaks). The car runs fine when port plugged but ofcoarse the checkengine light immediatley comes on. It's mounted to the firewall just obove the distributor and only has  wire plugs leaving and  vacumline into it.
