'88 Voyager Hesitation and Surging...

Voyager 3.0 consistently exhibits sluggishness, hesitation, and mild surging whether cold or warm. Recent tune-up, computer shows no codes. Engine known to be mechanically healthy, but driveability annoying. Have suspicions, but I am not a Chrysler expert. Suggestions welcome.
