Hey guys,

I have an '11 335i x-Drive (N55) and recently started having this issue where my first start up of the day is a rough idle and some stuttering. I have a tank 3/4 full of Premium Shell 93 octane and also filled a bottle of Chevron Techron Fuel System Cleaner before fill up. Car ran just like normal and even a little better afterwards. This is the third day it has happened but today it actually shut off after idling rough for 5-10 seconds. Next start up everything ran perfectly smooth.

When the car feels off I can go from 25-30% throttle to WOT and there is little to no power (cracked charge pipe?). Now when the car runs fine I feel the normal pull and the boost building when going WOT. This might be a separate issue but these symptoms all started happening at the same time. I do not think it is a HPFP issue, no cranking issues. I am leaning towards clogged injectors. Any other ideas? No CEL's have come on.

Thanks in advance!
