What could be the cause of a misfire on 1 and 4?

What is your question?

I have been trying to fix this problem now for a while and can't seem to figure it out. I have changed the coil pack and all plugs and wires. The miss hasn't changed or moved at all. When I am going down the road everything seems just fine. But when I stop I get a flashing CEL and have no power at all. Once it creeps past about 30-35mph the problems goes away again like nothing was ever wrong. Anyone have any ideas about what to try next. I'm tired of spending money on it but I love the van and don't want to get rid of it.
