Kwdriver84 Posted September 1, 2017 Share Posted September 1, 2017 I've had this issue for a while now. My 97 mack ch613 vmac 2 keeps shutting off radomly at idle and running and shows code 7-5.I changed the fuel injection pump hoping that would fix the issue. About two weeks it ran fine no issues now it started doing it again. Any suggestions are welcome.
