I have a 1993 Ford Crown Victoria LX. I've been having problems with it stumbling and hesitation. I brought it to a parts place on 4 separate occasions to get the PCM diagnosed. And they would give me printouts. EGR Sensor-Below Min Voltage,,,EGR Flow Insufficient,,,EGR Sensor-Above Max Voltage... I was told it wasn't the EGR Sensor, because a bad sensor wouldn't make the car run bad. So i'm thinking maybe the EGR Valve..Thanks.....
