ROUGH IDLE, SPUTTERS

1997 Nissan Truck • 110,000 miles

I have a 97 nissan truck witha 4cyl eng. When I first start it and let it idle will go from 800-900rpm down to 300-400 rpm then back also before it reaches operating temp while driving will hesitate and bog down. Once it comes up to driving temp it drives fine no bog down/sputter but still surges at idle. Have just replaced MAF sensor, altanator, and fuel filter
