Low Water Pressure - Kitchen Sink

I'm hoping that someone could help figure out whats wrong with my kitchen sink.

On Saturday morning, I was using the kitchen sink, when all of a sudden, it started to vibrate. I turned the kitchen sink off, and on again, but the vibrating happened again for a few more seconds. After a few times, it stopped vibrating but the water pressure/flow from the sink is definitely very weak. It is the same whether or not it is hot/cold water.

The water pressure in the rest of the house is completely normal. I did try to purge the water lines of any air by shutting off the main water valve, and then opening all the taps/showers, and then turning the main water valve back on. I then shut off all the taps, starting from the one furthest away. Unfortunately, I did that twice and it didn't do anything.

The type of kitchen sink faucet is the pull down sprayhead type. Unfortunately I don't know the brand.

Hope someone can shed some light on possible solutions! Thanks in advance!

That will be the diverter valve for the sprayer.

Replace entire faucet or it could be the aerator could be clogged.

Did you remove the aerator? Years ago, I had a similar experience and it turned out to be the hot water supply shut-off valve had a rubber washer that fell apart and clogged the sink aerator.
