I have an LCF that was driven in with a cold start complaint. It would not idle cold. Once it warmed up it ran fine. We replaced the injectors and corrected that. Now it starts and idles ok. Once it warms up it develops a skip and starts loosing power. I have run the performance sheets from Ford and Navistar and have come up short. All the sensors are reading properly. The fuel pressure is a constant 65psi. The high pressure oil system and sensors are good. No exhaust blockage. The egr is working properly. The fuel is good. The compression is good. Injector disable test shows nothing. The esn is 4.5HU2Y0272158. Any help in this would be appreciated. Thanks in advance
