I rebuilt a 1997 F250 5.4L engine and transmission recently and when i started it has a miss. I drove it and it misses all the time. I totally rebuilt the engine, new pistons, rebuilt heads, new spark plugs, new ign coils, new injectors, etc. I am thinking that the timing could be off but I did follow the details on lining up the dots with chain.
Does anyone have any suggestions before me taking the front of the engine off again!
