I posted awhile back of my truck smoking and over fueling at idle. I just replaced the 4th set of injectors yesterday morning and the truck is doing the same thing no matter what tune I run in it. At first it would run on a race tune but not any other but now nothing. If I play with it I can get the engine to warm up and it runs around 700 to 1000 at 60 mph. I can nail it from a 30 mph roll and it will clear up and white smoke the tires but as soon as I let off it starts white smoking again. A service manager at Ford tells me that the tone ring could have slipped and the engine is no longer in time. Is this possible? I have tried a few different ficms on the truck but haven't tried another ecm. I am going to borrow one tomorrow and try it. Is there anyway for the engine to be out of time?
