Hi To Everyone , I recently bought a 2001 Porsche 911 Carrera 2 Manual Transmission with a Bad engine , I recently rebuilded the engine and Now I have the Following Engine Codes , If anyone can give me any Info on what I need to do I will appreciate it . When I bought the car , The car didnt have any check engine light On, everything came out after I removed the engine to rebuilt it and Installed the Engine back . I basically Installed a New Crankshaft , Timing Chain , seals , Headers and full exhaust , the stock Catalitic converters are still in the car .
I also bought a DURAMETRIC Software and this is what it says :

1) FAULT CODE P1324
CRANKSHAFT 2 BELOW LIMIT VALUE
