Take this as a grain of salt as I am new to Porsche CIS but on all other CIS systems my approach would be this.

1. Grounds - clean up/replace/improve all of them.
2. Vacuum lines - A roll of the cloth coated line is cheap insurance and nice to remove from possible culprits
3. Reset fuel head and all WURs to factory settings
4. Retest

The worst situation I have gotten myself into was after I messed with too many settings to know anything.

Just my opinion.

Grounds are always a good thing to do though.
