1998 Ford F150 V8 Four Wheel Drive Automatic

Speedo started fluttering. Then stopped working. Replaced speed sensors still not working. Also when braking truck starts to idle rough. Also sometimes bogs down during acceleration. Replaced throtle position switch and cleaned mass airflow sensor. Ran better at first. But still does it from time to time. Any advice?
