1996 Ford AeroStar surging

My van is surging slighting at cruising speed. It's hard to explain what it is doing.Once you reach a steady speed, there is a surge or hesitation or flutter, it has plenty of power when you step on the gas and there is no sign of any problem, only does it's thing when at a steady speed
Any ideas on what we have going on?

1. check idle speed control solenoid
2. check for air leaks. vacuum lines/gaskets.
3. clean injectors.
4. how is air filter? You actually control engine power not by letting more gas in with gas pedal, but by letting more air in.

you didn't mention if you had a check engine light on or not but would probably check for codes for a starting point.
might also inspect the mass air flow sensor it may need cleaned.

Does the cruse control on your vehicle use a vacuum servo to move the throttle or is it all electrical / electronic ?

God bless
