Sounds like your pcv valve. Use some good brake cleaner and clean it out, it'll be nearly as good as one from an auto parts. I had that same problem, but I found out that the van isn't actually missing it is the touque converter locking in and out. The mechanic told me you can get a different chip for it but it will still do it at a higher speed (around 55 mph) instead of 45 - 60 mph and you lose 2mpg. Mine started bucking around 40 - 45 mph when I would go to give it about a quarter throttle or if I was going up a hill. It was just enough to jerk the vehicle to be annoying like a miss (and I was sure it was a miss but it wasn't it just felt like it). But he told me there is no real fix! As the van get older like the motor mounts getting older and the tranny plates wearing you notice it more but it doesn't really hurt anything. Mine drove me crazy cause the check engine light never came on so there were never any codes to read because it wasn't missing.
