Re: International 4400 power loss.
Of course they will check fuel pressure and road test it to see what the boost is. If this is low than they can run some other tests. They will be able to do a contribution test and if a hole fails than they can do a relative compression test. This is so cool as the computer does everything. It measures how fast the crank turns on each cylinder, if one is faster than an other than that hole is not builing up compression. So nice to not have to pull injectors or glow plugs out to take compression. When doing these tests they should the fuel rate and deviation on each cylinder. Have been lots of problems with injectors becoming weak and not delivering proper shot of fuel. Normally though the engine will have a miss and smoke.
If no problems found after this point and they find it also unsatisfactory than they will have to call Tech Central.
