Hi my name is***** will be glad to try to help. If it is throwing no ned codes and everything is in specs with the rebuild your next step is to reflash/reprogram the ECM with the most current software updates. You problem is most likely software related as the existing software learned the behavior of the engine before overhaul. If the ECM will not successfully take a reflash and update, replace the faulty ECM. Let me know
Thanks for the update. What are the fault code numbers you have? I should have some technical information but they are listed by the code numbers.
Okay. Sounds good
