K so i threw code P1128. Its for the engine running to lean. They say to check air hose wich i replaced last week. i also replacedan o2 sensor. I cleaned the MAF and the only thing that could possibly check is the vacume line, but i checked that and i couldnt see any noticible leaks, i am going to replace the vacume line this week end to see if this works. Any other suggestions? i am totaly lost.

 

If you have a vag com check your throttle angle at idle, if its more than 3% clean the throttle valve with some brake cleaner.
