Doug Stoker Posted October 21, 2021 Share Posted October 21, 2021 2007 mack granite cv713 tri axle dump with an Allison. Truck started to idle low couple months back. Idles at 500 rpm. Since then changed 6 injectors. throws a 8-3 blink code occasionally. changed that EUP, however still idles at 500 rpm. ABS light has been on for a while truck runs fine. Just cannot figure out that low idle. Any help would be appreciated Quote Link to comment Share on other sites More sharing options...
