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.....

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Provide the complete diagnostic printouts and symptom history to the repairer, and request testing to explain the reported faults before more parts are selected.

Next steps are editorial guidance for obtaining diagnosis or clarifying the reported findings; they are not a verified repair procedure or an independently confirmed component diagnosis.

Had similiar problem with a 93 crown vic. Ford company charge me a fortune and did no good. Finally found problem when changed plug wires and plugs. Know this doesn't sound like a solution to your problem, didn't think it would solve mine, but it worked. Just a thought to help you out.

Discussion summary

Missing Ford

A 1993 Crown Victoria had stumbling and hesitation. The owner reported diagnostic printouts describing EGR sensor voltage both below and above limits, along with insufficient EGR flow.

Reported outcome: No repair was confirmed for the original vehicle.

An EGR valve and oxygen sensor were suggested without test results. Another participant's successful plug-and-wire replacement concerned a different car.
