Default stuttering/loss of power

I have a 1999 Audi A4 2.8 Quattro 145000k... I am having problems with stuttering/loss of power. I have changed, Coil Packs, plugs, wires, purge valve/n80, MAF, and PCV hose. Still no change, Some days the car will run great and other days I get the stuttering/loss of power in all gears until I rise above 2500 rpm. Can anyone guide me in a better direction. Also getting codes p1136,p1138,p0411,p0441,p0300...I have looked up all codes and do understand the misfire and egr, but i am stumped on where to look further. I am thinking maybe a Sea Foam cleansing, which I have never done on this car.

i have a 2000 audi a4 and i was having a similar issue. i would be driving and power would drop out and it would stutter prity violently. i took it to a tech and they said maf. so i payed almost 5 hun for them to put it in and it still would do it. mind you some times it was ok some times it was realy bad. took it back they said ecu. i felt like that was a cop out. so i had a feeling it was fuel. i changed the filet and i was all good. the filter was clogged up. i think maybe some times the build up in fuel filter would get bad. choking off fuel supply. then blockage would clear and it would run normal.

hope that helps bro.

Mine was bad coil pack. Make sure you run high octane gas. I replaced my MAF about year ago, ordered it for 300.00 and threw it in. I cant be leave Dealer charges 500.00 for that. Thanks for the reply...
