Engine Performance problem
1992 Cadillac Brougham V8 Two Wheel Drive Automatic 127000 miles
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.
