2002 Dakota Quad Cab 4.7 and automatic trans. 206,000 miles

Engine seems to be surging at lower RPM once in awhile.
This morning when it started it was idling at 1150 or 1200 RPM then dropped to 850 RPM.

Setting at a stoplight it sometimes increases to 850 from 650 or 700 at idle in gear.

Anyone had this problem? No codes are appearing.
