Yes, Pull the faucet and look for particluate matter in the water passageways. Also check your shutoff valves, they have washers that fail, and then break up with you shut them off for faucet replacement, and little pieces get flushed into your new faucet....Kind of a common issue.

Hi jaryan--
Sometimes when you valve off a water supply, particles of rust or mineral deposits break free and travel along down the pipe when the water comes back on, only to stop when they reach a small opening. In this case, it could be the faucet's supply line.
You already cleaned the aerator, which would have been my first suggestion. The next step is to visually inspect the supply lines for the faucet. Are any of them kinked or twisted? If they look good, the next step is to valve off the water at the shutoff valves closest to the faucet-- they should be on the plumbing under the sink.
Next, disconnect the supply lines to the faucet at the point closest to the faucet. Using a bucket, aim each supply line, one at a time, into the bucket and slowly valve on the water. How is the water pressure? Do any rust particles come out? Flush each line until the water runs clean and strong. Before you reattach the supply lines, use a flashlight to check the hardpiping on the faucet itself and visually check for any obstructions. Remove any suspected blockages manually.
Reconnect the supply lines to your faucet and check its pressure again. If the faucet's pressure is still low, you may have a clog in the faucet's interior mechanism.
--Hope this helps

We have the exact same problem with a moen banbury that is about six years old. There is plenty of water pressure everywhere in the house except this faucet. There is also plenty of pressure when using the side spray. The hot and cold valves barely run a trickle of water when turned on that slowly gets stronger. Checked all the valves and water passages and all was fine. Still not fixed.
Finally figured out the problem with help from moen. A part called the diverter needs to be replaced. Moen sent it free - I installed and it works. Pressure is fine and the side spray works. You can also remove the diverter altogether and the pressure is fine but the faucet runs while using the side spray.
