My 3.0 just threw flashing cel in the rain. Rough idle, loss of power, flashing and solid cel etc

Last week I had new plugs, oil change, new filters and new cam position sensor. It ran fine for one week. After sitting all day in the rain, car drops power at light and gives flashing cel.

I pulled over into lot to check. I let it rest, same thing.

I won't get the codes until I get it towed to the shop tomorrow.

Ideas? What water fouled thing could have happened between the shop and now with it running fine in between.

Thanks in advance. I'm looking for info so I can figure out if it is something new or the shop scrwwed up the first job!

any ideas?

shop answer: coilpacks

3 failed coil packs. Replacing now.

what would cause this? can you damage a coilpack when changing plugs?
