started van up other morning, rough idle then smoothed out in 15 seconds and ran fine..... next day CEL on and both misfire codes showed...2 and 3... van ran fine, still does, light went out yesterday and van still purring nicely..., but I am taking big trip next week and want to cover all angles... 116000 on van.. 3.8.. ideas..? coil failing ? new plugs and wires 20000 ago... thanks

 

Cylinder misfire in cylinders 2 & 3. But only on first 15 seconds. I'd be checking around Plugs and Cap. But I don't think you've got a Dizzy. Check plug heads/connectors are tight fitting.
