Actually it should take no more then 5 minutes
To change the #1 coil &only that long cause
you have to remove the engine covers

See the spark plug DIY threads, it explains how to remove some of the coils if they are in a tight space. I didnt pay attention and actually broke one of them while forcing it into the hole. It was much easier after I followed the thread.
Im not sure, but I think you can run the engine and disconnect each plug by unplugging the coils one at a time. The one that doesnt affect the engine is the broken one usually. Alternatively connect to an OBD reader and google the code for the cylinder number.

Also make sure you don't have a vacuum leak it can also give you a rough idle.

Do you know where all the vacuum lines are? I've replaced a few big ones but can't find any others besides three big ones and a couple little ones up front..

Also, I like the way your car looks, what kind of options did it come with? My car is a silver color, but not as light as yours.

Only vac lines are on the pump, the elbow boot from maf and one of them goes from the plastic union (look on top of left/driver side wheel well area in engine bay) down to the left/ us driver side down to the pressure regulator on the fuel filter, the other i didn't follow to see where it leads
