I need help i have a 2001 Land rover discovery 2 and i put a code reader on it because was running rough i got 1319,1300,1590,p0307 and p0302 i know the 2 last codes but the 3 first are manufactor codes does anyone know the meaning of those ? Thanks

 

There is a hand full of codes. The 1300 code also has to do with misfires, the other 2 I am not able to find.
Tell me what your truck is doing and how many miles on it?
