Loud sucking air noise when full throttle

Post by **boxcarbill** » Mon Dec 02, 2019 4:56 pm

I noticed this a couple weeks ago on my 2007 Versa after I had my oil changed at Valvoline Instant Oil Change. It's quite loud. The car seems to be running fine. Fuel mileage seems the same.
If I floor it at 2k rpm or higher I get this noise.
What is it?

did they check or replace the engine air filter? I am guessing it may have something to do with that, I could be totally off though.

I told them not to touch the air filter and was sitting in the car when the oil was changed. I'm pretty sure that's not it.

It's looking like a high frequency clicking sound and not air now. Possibly a bad fuel injector?

are you getting a check engine / service engine soon light?

No.
I watched a Youtube video and the Nissan (not a Versa) made the same sound when the throttle was down past the half way mark. The guy driving the car was a mechanic and he said it was a bad fuel injector.
