Re: Moen Faucet
Turn off the water, pull the cartridge, then put a towel over the faucet and carefully turn on the hot side to purge the line of any debris. Reassemble the faucet and see if that takes care of business. If not, disconnect the hot line to the faucet and run it in a bucket and see if you've got full pressure through the hose.
If you have good line pressure, then replace the whole faucet assembly. Personally, I've never been a Moen fan, they seem to be a cheaply made faucet wrought with problems. Pfister and Delta are good brands.
