Recently my van has not been accelerating smoothly. When I'm accelerating past 30-35 mph it starts to pull a little. What might be the problem?
 
How about try checking your tire pressure.

Probably not, but when my car pulls it is almost always because one of my tires 5-10 pounds under.

It could be your alignment is off too.
 
This can be many things.
If you are refereeing to pull as in to the left or right that would be alignment, tires and or both.

If you mean loss of power that leads to a whole new set of possibilities.

Transmission, engine, vacuum leaks, EGR valve and half a dozen other sensors.

Unless you know how to diagnose these things the best way to find out is take it to the shop and have them figure it out.

First thing you might want to do is pull the sparkplugs and determine if all cyliders are firing and also determine if you are getting the proper air fuel mix based on the plug color. that should point you to the next step.
