Hard start when hot points to a few things. In particular a very dirty air filter or poor battery connections, especially the ground. If you check those two things and replace air filter as needed and clean up battery connections things shouldimprove.

i just bought the car and it runs really good besides that issue,now i see that the cables are in good shape,it seems to have two wires on each side,the positive runs straight down to the starter and then a second wire goes toward the firewall,the negattive grounds right next to the battery and also has a second wire...what are these for??

with the motor running, pull the vacuum line going to the fuel pressure regulator, look, feel and sniff for fuel, chances are you have a bad FPR, symptoms, easy cold starts, hard hot starts
