Hi All,
I just replaced my 2018 L83 engine with a 2015 L83 as the 2018 dropped a lifter. Some background I used the engine harness from the 2018 with the exception of valley cover wiring harness (fuel injectors/ect) and the timing cover harness (cam sensor / oil pump solenoid). It runs and idles but has "Reduced Engine Power" on the display. I haven?t driven it yet as I?m concerned about the reduced engine power. After some more research it looks like there might be a pinout difference between years. Any thoughts or advice would be great.
Thank you
