maybe this will help

-PCM is flashed to the latest calibration?
-Injectors can cause a miss, rough run or surge when cold if the spool valves are sticking. There is currently a re-flash to operate the injector spool valves during the glow plug cycle time in order to free up the spool valves. Excessive oil change interval can cause the spool valves to stick.
-perform a relative compression test and a power balance test to verify miss on a particular cylinder.
-Low fuel supply pressure, particularly when cold. Fuel supply pressure should be 45 psi minimum, KOEO and 45 psi minimum on WOT hard acceleration.
-Check valves in the high pressure oil circuit that feeds each injector rail can break.The check valve (snubber) plates have 3 small tabs; if any of the tabs are broken they can stick in the oil inlet to the injectors. You will need to flush the oil rail to find any missing tabs.
-Dual mass flywheel bad (used in 2003 & 2004)
-FICM if bad should miss at all temperature ranges

Injectors
-PCM at the latest calibration?
Bad injectors can cause a surge, hard start, cold rough run, low power, black smoke or a miss. Address oil and fuel maintenance issues and aeration before replacing injectors.
-Injector installation is critical, improper torque will cause injector chamber gasket failures.
-Injector chamber gasket failures will result in aeration in the fuel from combustion gases.
-Failure to remove the oil from the hold down bolt hole will result in improper torque.
-Broken injector stator housings, when the two bolts that holds the stator housing to the injector body break, are caused by air in the fuel.
-2004 1/4 vehicles need to update the stand pipes when replacing injectors
