Why would just the kitchen faucet sputter when first turned on and no others?

If this faucet has a spray hose, turn on the faucet and open the spray hose.This will adjust the diverter in the kitchen faucet to the spray and pressureize the hose.This will allow the faucet to equilize and the sputter will stop if the spray diverter is working. It could be that the diverter part in the faucet is defective.
