Did you readjust all the valves ?
reset all the valves to .010"
Is every thing properly bled?
If so take the side cover off the fuel injection pump and check for stuck pump lifters.
I bled everything to the injectors, and had the same amount of fuel at all 4 injectors. I did look for stuck pump lifters all seemed ok. Fuel pressure was lower than it was the last time I ran it (1.5 years ago), now only in the white range. The exhaust was all white smoke and a lot of it and never cleared up. Just think it's funny that it ran better on 3 cylinders than it does on 4 lol.
