93 civic lx d16z6.. no check engine everythings fine

Check engine light ?
Warm it up and check fuel pressure and spark see if they come back satisfactory / within factory specification.

 

I think any car will start to feel like crap if its overheated.. is your radiator fan working? is it cooling it down?

yeah fan works normal cooling yes

 

You need to describe in more detail what is going on. Also, please write more legibly.
