There is a device inside my Quadrajet with two wires coming out of it. What is it? It is a non-computer controller carb (no "dancing needle" linkage and no throttle position sensor). It is in the same location that the mixture control solenoid is in on the electronic Q-Jets. One of the wires coming out of it goes to a temperature sensor in the water neck. When the truck is idling, I can pull the connector out of it and nothing seems to change. "All right...who keeps squirting this oil in my driveway?"
