When I start the car cold it seems to run rough and won't go over 25 mph once its warmed up to running temp it goes ok but has little power taking off then at around 3000k rpm it takes off like a bat outta #$%%. I replaced the injector seals and replaced the maf 3 times with vw OEM sensors it didn't help actually it made it worse so I took it to vw and had them do a diagnostics. They found a hole in the hose coupling on the pressure outlet so I replaced that but I'm still having the same problem but it runs like it did in the beginning. The maf is good for sure the only scanner I have is an actron and even with the new maf it throws the code for mass or volume air flow circuit range / performance. I've cleaned the intake and egr, the egr isn't sticking I've checked that twice I replaced the cat it was clogged I don't have access to a vagcom or vcds so any suggestions? Oh I also replaced all vacuum lines they also came from vw.. I just don't know what else to check the turbo and actuator is also good the turbo was just cleaned.
