Research on RPM DROP on AUDI A4 v6 3.0L- Replace PCV valve and Ignition Coil packs

1. interchange spark plugs with the misfiring ones -
   - recheck the code and notice if the misfire codes move to different cylinder
2. Interchange Ignition Coil packs
   - Recheck the scan codes if they change and if it moves to different cylinder
3. A broken PCV valve can also be the reason. (Check the Intake Mainfold Runner Motor)

The most common ones are:

PCV

Intake Manifold Runner Motor

Fuel Pressure Sensor

Might be missing one.

Just had the first two done a few weeks ago, car is driving better than ever!
