If a car has a loud humming noise when accelerating, it could be that the air filter is missing. The air filter housing might also be loose. A loud humming noise can also be a signal that there is something wrong with the alternator belt or the fan belt.
Answer Humming noise from front endI just got my car fixed with the same problem and it was the wheel bearing and it is gone. Was it a fwd car?
wind noise
Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
noise and jolting is present whilst car is idolling and accelerating
bad wheel bearings
You may be hearing the coolant passing thru the heater core with an air pocket trapped in there.
when you turn your key and you only hear humming noise, the problem will most likely be that the starter is not engaging the fly wheel, its turning but is not sliding forward to do its job. have the starter check.
If it sounds like its coming from inside the car its probably the fuel pump if not its kind of hard to say.
The humming is a series of explosions in the engine happenning very quickly. Could also be an electric fuel pump if the vehicle is equipped with one.
That depends... What does the noise sound like? Where does it seems to come from? Does it only happen at certain speeds? When shifting gears? When braking? When turning? When accelerating? Is there a vibration with the noise? This question can not be honestly answer without being a lot more descriptive. My car is making a clicking noise when accelerating...it sounds like a can of marbles...what can be causing this to happen. It has been doing it for 4 years and no one seems to ever know where it is coming from. Could it be from the crankshaft? answer mabe the cam shaft or the lifters not the crankshaft more likely to be a leak around the exhaust manifold
a humming noise is usually related to the fuel pump about to go. or u just have a really loud fuel pump and everything is fine.
