there should be a sticker beside the fuse box on the left side of the car (drivers side in canada) it shows vacuum hose routing, as to the high idle, check the idle screw and the throttle switch (black box with a wire coming out of it located on intake manifold, opposite to throttle linkage) This throttle switch can be adjusted and may be holding the throttle plate open. There are two (or three?) screws on the back which can be loosened and will enable you to move the switch back and forth. It should be adjusted so that you hear a click when you press the accelerator.
