Suggest you read the first link below in my signature.

I did not hear any mention of the DISA O-ring or DISA being inspected, this is a big cause of cold start misfires after the car has sat for overnight or even longer.

Also you need to make sure your engine is not running chronically cold, this can lead to excessive carbon build up that causes cold start issues as well.

Read this thread -

Also make sure your engine coolant temp before you start the car is at or below ambient temp, if higher, this is an issue that may need to be addressed.
