Question about Porsche Cayenne
Only certain things can cause a miss only on one cylinder . faulty spark plug, faulty fuel injector, faulty coil, vacuum leak on intake manifold (plennum), valve issue, or head gasket issue. Being a low milage car would I would suspect possibly a clogged fuel injector or the spark plug.
The purpose of using a diagnostic scanner is one would be ableto rule out most of the possibilities looking at the data.
All you can do is replace or rotate the spark plug to see if the code folllows the plug and add some chevron techron fuel injector cleaner. Also use chevron 89 or 91 for a rew tanks because the fuel cleaner in thier fuel seems to be the best option for cleaning injectors and keeping them clean.
