I am really tired of this

Thanks for your replies.
Both sensors were changed 3 months ago, car ran fine for about a month or so and then the problem came back slowly, to the point where it is now. Don't know about the other sensors you are talking about Robbie, do they have a different name for Audi?
The MAF is a pretty expensive part to get I think, especially if it is not sure what kind of impact it will have.
I let the car sit overnight after what happen yesterday and tried it this afternoon. Started fine, ran on idle for a few seconds and then started to be unstable, I gave it some gas, RPM boucing again, not able to reach 4000 RPM or to get the engine to wind up properly, and then if I gave it some gas, it started backfiring (for the first time). The new thing about this is that it happen when the car was cold, a few seconds after startup...
