1993 Chevrolet Lumina APV 3.8L MIL Lamp on
Customer had this one diagnosed at a dealer and had requested egr valve replacement to get the MIL to turn off. Now we are getting these two codes for 47 uart link prob, and 56 QDM 2 prob. We have no idea what the 47 is for. All Data gives us no clue. Any help...
