I need help figuring out my truck. It had a knock when I got it so I replaced the injectors. It was not smoking at all except on start up.
Now its rough idling knocking and smoking pretty much constantly like this. also feels low on power. I checked coolant and it is good. also checked for cavitation. Also I know my cdr valve is bad but it wouldnt cause this much of a problem. I had a leaky return line and 2 kits later I finally have that sorted and sealed. Got reman'd injectors from pensacola diesel. Thinking one or more are bad.
