A good running 2006 1397 , I just had engine out and added the APE Gen 2 crank, ran great before. Now it acted like rev limiter and went flat at upper rpm, threw C-24 and C-27 codes. Plugs looked good, swapped coils --no change, swapped ecu--no change--- ran coils off separate relay-- no change, swapped stator and crank sensor-- no change, pulled cam sensor and it revs way better but still throws those same codes, will let it cool off then pull cam cover to check cam timing and pin height.
Any input??
