humming sound

friends, yesterday, let me take care of my air conditioner, I thought I had a leg in the air conditioning compressor, it changed the level of the gas, it flattened, I went to the exhaust at the bottom of the exhaust at the bottom of the exhaust sensor, I went to the exhauster, I boiled, then the car started to be a humming sound when it is running, it is not heard from the outside, but it is not heard from the outside, there is a sound that is not heard from the outside, but it is not heard from the outside. What are the masters?

Did you weld the bottom of the oxygen sensor?

As far as I know the bottom of the sensor after the catalyst, the place called the second sensor boiled after inserting the sensor

Does the steering wheel increase and decrease when turning the steering wheel to the left and right

I never noticed it but it comes in rolent

Well, when I boiled the crack, the sound of the car decreased a little more than before. & Nbsp;

Yes, the sound of the car has decreased but I am sure that there was no water first, there was water, right, ten tires next to me, I think there is a steering oil tank.

[QUOTE = riva70] yes, the sound of the vehicle has decreased, but this sound did not exist first, I am sure there was water, right, right on the tire, I think there is a steering oil tank, it was shaking and making a sound, I asked the master, he connected him with a smart handcuff. [/ QUOTE]

I tried this day when the steering wheel was left or right left, the sound is different.
The steering oil tank was shaking, I fixed it.
