I have p1380 and p0300 any ideas to fix i had this problem for a minute

 

The computer has detected random misfire. This is usually due to a lean fuel mixture, so check the fuel pressure with a gage. If that is good, make sure all ignition parts are up to snuff.

 

ok i brougt a autozone distributor and put it on then coolent leaked on it i dont no if that made it worst but it drove no different fom original distributor so it had me guessing the a friend off mine just swaped for ls1 so he gave me his oem distributor and it drives way better but still have same miss fire code p0300 and also p1380 it dives good cold but when warm it start missing harder i have duralast wires from auto zone and ac-delco rapid fire plugs so do anyone have ideas on p1380

 

Have you checked the fuel pressure with a gauge??
