Hi, new to forum and have a problem. I have a 2004 mack cx 613 with the aset 427 engine. I have a generic code scanner and it keeps poping out the same codes but I dont know what they mean. I wasn't sure if anyone knows what these codes mean or what the problems could be, but I lose power and I have black smoke sometimes. The first code is 128 018 4 SID Engine #1 fuel control valve below normal or shorted low. 128 013 7 SID Engine #1 injector cylinder #13 mechanical system not responding. The 3rd is 128 254 4 SID engine #1 controller #1 voltage below normal or shorted. 128 156 0 PID Engine #1 recirculated engine exhaust gas temperature data valid but above normal operating range. I would appreciate any help from anyone who knows what these codes mean or what I should replace to fix my problems. thanks
