If you own a 1991 Supercharged 3.8, your car does not have an EGR valve. Take a look under the hood at the vacuum diagram. It won’t show an EGR or vacuum line. I just spend the past day, attempting to determine if mine had one. If you look for that part online, you will find it. My parts store even ran the VIN and sold me the part. Most auto parts stores list an EGR for the SC.
This may not be true for other year SC’s and the Ford 3.8 non SC does have such a part. I’m in California, and dealing with Smog issues on my ride that has 41,000 original miles. Car is rarely driven… CA should exempt low mileage vehicle from their silly inspections! …Now, on to find the culprit for the High NO reading. Hope this saves someone else some research time.
