Hello All,
I am a new member here looking for some advice. I found some threads with solutions to similar problems but wanted feedback before I start tearing my car apart.
Vehicle: 2006 MS6 with CorkSport Intake and MAF / Vent-to-atmosphere BFV / Muffler Delete
Some history: I have had the vehicle since roughly 2017. No issues for maybe 3 years. It eventually picked up a very very minor stutter that most would not even notice but no CEL. I moved to Michigan where the car mostly sat in the garage all winter. I always put Stabil in the tank until last summer when I "believe" I forgot to add it. 1 year later the stutter has worsened.
Latest status: CEL for P0300 came on. New NGK Primary O2 sensor and NGK iridium spark plugs installed (no change to stutter). Cleaned MAF sensor (No change to stutter). Fresh tank of gas with seafoam (no change to stutter).
I have attached a link to the logs of what I believe is the relevant information (AFR/ Throttle/ RPM/ Intake Manifold Pressure, etc). Also some of the throttle readings seamed off.
*Also, at mid range RPM's, Im occasionally hearing what I believe is turbo flutter (not my BFV)*
Any help is greatly appreciated!
