ok for one i need to know about the 4WS is there any grease points that i have to grease and where are they at. or what do i have to do maintenance wise to make sure it don't go out. and # 2 it overheats after i drive it like 20 min. i put a new thermostat in it. i don't know if its the head gasket, water pump or if the radiator is just bad. what else could it be? and # 3 when i start it it acts like its not firing on all 4 cylinders but when i rev it up it starts sounding better. i have been running injector cleaner through it and it helps for a little bit but it just starts back up again. and it has new spark plugs and wires so i don't think it would be that.
