Fuel Fail 39 via VCM in August. I pulled a EGR out of a 93 at the boneyard today. I used some fine sandpaper and a file to clean the sensor, cleaned the copper washer as well and installed in my beige 90 VDP. Check Engine light is off for now and no code. Lets see what happens. $3 part

 

Well it surely looked nice riding without that check engine light, but it came back on, same code FF39.
