Anybody have an idea as to what I could run through my fuel system to unstick an injector? One of them is sticking on, pretty much all the time I think, I have good deal of whtie smoke out the stacks that smells like raw fuel. Looks like a 6.7 thats trying to regen without cats. I am going to run some biodiesel through it once I run the tank down, but I want to see if anybody has other ideas. I do run Power Service in pretty much every tank.
