Why does my car sound like it's leaking air?

If your exhaust system has a leak, you will hear exhaust noise coming from under your vehicle that is loudest when accelerating. The noise means a muffler, pipe, exhaust joint, exhaust manifold or manifold gasket, or the catalytic converter has a crack or hole and is leaking exhaust.

This Noise Means Your Car is Screwed

When I press on the gas I hear air?

Usually this type of noise in an indication of a exhaust leak or a vacuum leak due to a broken or disconnected vacuum line. If you also notice that your car is slow to accelerate or is running rough, then it is likely that one of these items is the root cause.

Why is my car hissing when I accelerate?

If the hissing happens when you accelerate, it could instead be a vacuum leak from one of the small hoses around the engine's air intake.

Why does my car sound like a race car when I press the gas?

If you notice any rattling or whining sounds while you are accelerating, this could mean that your camshaft (timing) belt is poorly aligned or slipping. The timing belt synchronizes the turning of the crankshaft so that the engine's valves open and close at the proper time.

Why does my car sound weird when I accelerate?

A loud squeaking or squealing noise while accelerating could mean there's a problem with your engine belt. It could mean the belt's loose or worn.

What happens if you drive with a vacuum leak?

At its worst, long-term driving with a vacuum leak, elevated temperatures generated by running a lean air-fuel ratio could result in engine damage. Lean mixtures can detonate, damaging pistons and bearings. Higher than normal exhaust temperatures can also lead to catalytic converter meltdown.

Is a vacuum leak expensive to fix?

Depending on the cause and location of the leak it can cost between $150 and $1,000 to repair a leak in your vacuum system.

Why does my car sound like a lawn mower when I start it?

If you request a vehicle noise diagnostic the origin of the noise will be pinpointed and the certified mechanic will let you know of the required repair and the cost.

Can a vacuum leak cause hard starting?

At its most severe, it can affect transmission shifting to the point of damage, or the vehicle may fail to start at all. Typically, a vacuum leak will cause situations like hard starting, rough idle, excessive fuel consumption, and engine codes.
