64C85 Posted August 25, 2014 Share Posted August 25, 2014 I believe it 128 = engine, 13= injector #1, and 07= mechanical issue. Therefore you have an issue with your #1 injector. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/36823-code-128-013-07-trouble/#findComment-257332 Share on other sites More sharing options...

wheeler73 Posted August 26, 2014 Share Posted August 26, 2014 It is usually the eup. The injectors do not throw codes as they are mechanical. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/36823-code-128-013-07-trouble/#findComment-257380 Share on other sites More sharing options...
