Quick Question about EGR Valves. . .
Are the EGR valves in our cars spring loaded to the open or closed position and then the energised solenoid moves the valve AGAINST spring pressure? :?

It'* neither. Your valve (94 and newer) is a linear actuator. It uses pulse-width modulation to open the valve for varying amounts of 'on time'.
The 91-93 are a digital EGR with three separate solenoids, each opening a different diameter orifice. It uses combinations of these to get the correct flow.
