I traveled and I parked my car for four months, now it cannot accelerate when engage in gear. I have changed all the plugs, fuel pump, service the injector and still giving me same problem, no matter how I accelerated it and will not be more than forty km/h while it makes the engine very hot.

The transmission is not up-shifting and you would need to have it checked. After being parked for extended period of time, the solenoids could be stuck resulting in transmission not functioning correctly. A diagnostic scan should provide you with some clue.
Do not attempt to drive harshly under such conditions. Be gentle with the accelerator and if after some driving the problem still persists, you should get professional assistant. Servicing the solenoids might help but some might need to be replaced if servicing them do not work.
