Default 2007 Q7 4.2 L engine problems..Help!! please.

I started having problems with my 2007 Q7 4.2 L late last year, when I floored the pedal and nothing, only high RPM reading but no monster acceleration like I was used to. The check engine light is turned on. When running in the city at normal speeds, all seems normal and the car runs fine. It is only when you force it at high speed or when going uphill that it stalls and you get no acceleration.

So far I have done the following and I still have the same issue at high RPM:

- Changed all spark plugs
- Changed all ignition coils
- Changed all O2 sensors
- Changed the 2 high pressure fuel pumps with sensors
- Checked for vacuum leaks and nothing appears

I am still getting the following error codes:

- PO304, cylinder 4 misfire
- PO302, cylinder 2 misfire
- PO303, cylinder 3 misfire

Can anyone please give me any clues on what to try next?? My bigger problem is that I am at a town in Bolivia South America, with no Audi support whatsoever, so I have to rely on parts brought from the US.

Thank you very much!!!
