for the object problem:
this below your current code:

pawn Код:

SetTimerEx("MyRemoveFunc", X * 1000, false, "i", playerid); //replace X with the amount of seconds before the object should be removed

and this somewhere out of any callback

pawn Код:

forward MyRemoveFunc(playerid);
public MyRemoveFunc(playerid)
{
  RemovePlayerAttachedObject(playerid, 0);
  return 1;
}
