hey guys, just purchased an 85 6.9 4x4. I have replaced all the injectors on it due to the truck "running" off on me some.
Here re is the issue. It runs great and smooth at idle and for about 25 minutes while driving. Then all the sudden it starts to have an injector knock and massive amounts of smoke blowing out. During this time it will sometimes try and run off but not much and then eventually it will basically die and won't start again until it sets for a while.
My my thoughts are that it is the injector pump, maybe a seal or something but don't know much about the pumps. I am familiar with the engines though so I understand it.
Anyone got some some possible pointers or ideas?
