I have noticed a groaning noise when accelerating in my 2017 Camry which has 107,000 km on the clock.
It may be coincidence but I only noticed the noise after changing the engine air filter .
The noise isn’t noticeable when revving the engine when vehicle is stationary ?
Any ideas what it might be ?
Thanks

 

Was this a DIY filter change? Is this a paper filter or a screen/foam/oil type?

The noise wasn't there prior to the filter change and was after the change?

The air intake system incorporates a good deal of design to minimize air intake noise.

Make sure the new filter is installed correctly and the filter case closed properly. There may be an air intake temp sensor that goes into the side of the filter case. Make sure its plugged into the case. Check the engine air intake hose for cracks. The air intake system might be complicated as part of sound reduction design thus make a careful check.

If you have the old filter swap it back in.

 

I checked and realised I hadn’t closed the compartment properly at one end .
Its all good now. Thanks very much .

 

Great!

Thanks for posting back with the fix.
