I have a 2010 Nissan Altima (gasoline engine)

I hear a slight ticking sound when the car is accelerating. The ticking is in tempo with the RPMs.

It only ticks before the car gets completely warmed up: Only for the first coulple of minutes.

There is no ticking when the car is coasting.

There is no ticking when you put the car in drive, hold the brake and press the gas pedal.

There is no ticking when the car is in neutral and you press the gas pedal.
 
What is causing this?

Thank You.

Noises are hard to diagnose without hearing them. Can you pinpoint the location of the noise? You may need to take it to a shop that can drive it and isolate where the noise is coming from.

If I had to make a guess just going off the info provided, I would say it sounds like you have an exhaust leak, probably a gasket.....

With exhaust leaks between cracks & bad gaskets..... a crack usually gets louder as it gets warmer due to the crack expanding & getting bigger.. A leaking gasket (small leak) will be louder when cold and the quiet down as everything heats up and expands, sealing the leak a little bit better....

Now obviously once the gasket gets bad enough, it won't quiet down anymore but in the early stages can get quieter after warming up
