Faucet water pressure problem

We recently purchased a Grohe Kitchen faucet. We installed it. We have plenty of pressure coming to the faucet, but the flow from the faucet is very low and seems to be getting lower. We backflushed and have dismantled several times. We can't seem to get minimal water flow from the faucet. What it seems like is that there is a flow adjustment that we are missing.
Help!

Remove the aerator on the end of the faucet and try it. The aerator screen often gets clogged whenever you're messing with sink faucet plumbing.
If that isn't it, dismantle the faucet, lay a towel over it, and turn the water back on briefly to flush any debris that may have gotten hung up in the faucet body itself.
Good Luck!
