Everytime it rains my van chugs sputs and spurts What else do I need to check and replace
Could be jumping spark some where. This tends to be very noticeable in rainy/foggy/damp conditions. Next time it starts acting up look under the hood for spark jump. Can only be seen at night with no lights shining on top of engine. (Perfectly dark) If this is the problem you will see blue spark jumping from either a coil, distributor(if equipped) or plug wire. Hope this helps.
So then do I change out the coil, PCV, or distributor
Repair or replace the item that you see jumping the spark.
