Hey guys got an issue here and in need of help. Got an 04 f450 runs ok cold but loses power at operating temp. Specially in gear no power and hardly no throttle response. I've checked the ficm and checks out good, both batteries are new and alternator is also new. ICP and IPR valves seem good as well. Been doing functional tests with scanner, found no difference when disabling injectors 2, 4, 6, 8 individually while engine is hot but found a difference when engine is cold. Any ideas??
