i changed the plugs, coils, mass airflow censor and fuel filter still having same problem noticed when i don't give it a lot of gas it isn't as bad.

Ive also changes the same on my 2000 Audi TT quattro except i went to autozone and got the fuel pump diagnostics kit and check the fuel pressure..Mine didnt depressurize like the book said it should of so it said to replace the gass pressure valve..Well it help but didnt fix the problem. So im still looking into it if you find the answer let me know please..if i get it ill let you know asap. The only thing left i can think of is faulty injectors. My problem started after i put injector cleaner into my car so it probably lossened something up.
