probe the middle red wire. Turn the car to ignition on but dont start the car. At closed throttle the reading should be around .5v. At wide open it should be about 4.5v. Sometimes the VSS sensors go bad if coolant gets down on them too much. Try drying it out real well if you spilled coolant on it. Try replacing it. You can source them off any b or d-series transmissions.
Also make sure you don't have the map and TPS plugs switched around.
good kill!
