EGR Flow Insufficient code
My son has a 95 Ranger with the small 4 cyl engine and is getting an error code indicating the EGR flow is insufficient. I forget the code number but we have replaced the EGR valve and the sensor. The hoses look ok and are connected properly. He gets the code after about 70 miles of driving. My question is, what controls the EGR, the computer? Is there any other parts that could be the culprit for this problem other than the computer? Our next step is to blow out the sense lines, maybe they are plugged? Any assistance is appreciated.
