advice time kids, I'm out of ideas and parts to replace
Consistently getting a very lean (+20s) LTFT on only bank1 and only on high RPM.
Eventually stumbles and throws a CEL for P0171 and the random misfire if I keep it pinned at WOT. Idle is fine, cruising is normal.
Replaced much of the intake, including all upper and lower gaskets, plugs, coils, still no change. Thinking of doing the brake booster but that seems fine. Plugs look OK, no oil, no foul.
Haven't smoked it out yet, because this only happens at high RPM, and thats kind of hard to do on this car when its not moving...
Maybe injectors??
