anyone had this happened?

gaspedal on -> off on high RPMs making "buck" sound...
and several times of on->off->on->off quickly makes CEL...
P0302????

Also with having no problem with starting in Cold engine temp,
but having problem with starting in warm engine temp. (takes much more than usual)
Like, starting the car again in 10 mins after engine turned off. engine temp still
remains.
Changed all wires, all coils and all the plugs tho.

Is this a momentary CEL? If so it may just be the infamous random misfire. May be caused by a bad spark plug or coil, or just a momentarily-confused ECU. However, hard starts of warm engines smack of low engine compression. I would strongly suggest that you get the car to a dealer soon for diagnosis.

Edit: Here's the diagnostic sheet from the factory manual for P0302.
