Fuel pressure is good on the rails...reading 42-50 from idle and into boost.
Dropped new 104's in and did a fuel trim reset (battery pull overnight).
I have not seen the code come back since. Must have been a hairline crack in a plug since they only had 500 miles max on them.
A slight misfire or injector issue uptop @ WOT, but I think it is still related to the gas and cleaning out the injectors from sitting all winter.
After this tank I plan to seafoam and then I should be ready to rock for the summer.
At least the code is gone and the engine runs 95% like it should. Fuel trims are -0.7 to 0.7 so the tune looks good still and knock is still under control with small blips of 1-2 at the very top end under WOT.
