when the engine is newly turned on, it produces strong vibration and it sounds like a diesel engine even though it's not. para tumigil ang vibration, kailangan pang buksan yung aircon o tapakan ang gas pedal kundi may possibility na mamatay ang engine kasi umiilaw yung warning sign for a drained battery. problema ko rin yung white smoke from the muffler when the aircon is turned on.
Try mo pa tune up yung car, palit spark plugs kung carb type linis carbuerator.
White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event.
