I've been working on my 280zx for quite some time now, off and on whenever i can spare the money, after replacing the fuel pump,starter, fuel injectors, fuel filters, clutch and a new timing chain, the car will start and idle fairly well. however whenever i get it going it will begin to hesitate and "nosedive" once it reaches operating temp. and the rpms hit around 2.5. i'm not trying to break any land speed records i would just like it to operate as it should. i'm at a loss as to why it is doing this and would greatly appreciate any help. my cousin believes it is the synchronizer but i do not know much about the inner workings of the transmission so i have no idea... any suggestions? thank you.

I recently changed the fuel injectors on my 1980 280zx, and now it will not start, the fuel pump is working and there is pressure in the lines. The engine will crank and begin to turn but never fully turn. Prior to this the engine would start i'm at a loss, any help would be appreciated. Thank you.
