we have a 05 F550 wrecker at work that runs like crap, what i mean is the thing wont get out of its own way when its cold, when it warms up it runs alot better but still has a defined "miss" in it, i've read somewhere that the FICM is the culprit most likely but where is the damn thing? i replaced a turbo on the thing about a month ago after teh seals started leaking. The high pressure oil pump was also done just before that, even though it didnt need it but the hero said it needed one and it ended up being the frame pump. The truck only has 61000 mile on it and we are about at wits end with the thing. Have had ford reflash the PCM and all on it about 2 months ago, seemed to help somewhat.
