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

 

A new distributor will not be affected by some coolant leaking on it. The seals are new and should prevent coolant from leaking in.
LS engines use a completely different ignition system.
Does your check engine light come on? What you are describing is when your engine gets warm, what you probably are experiencing is the engine going into closed loop operation. It is running poorly when in closed loop.
You probably have a poor connection in your wiring causing the "rough road data" problem. The sensor(s) are getting an intermittent signal.
I cleaned all my connections with electronics cleaner and then smeared dielectric grease into the connection before I plugged them back in.
