Full lean AFR at idle only
Well out of nowhere my AEM gauge is showing -- at idle, which is full lean 17+. This happened out of nowhere. I am going to do a boost leak test tonight but wanted some ideas.
WOT is dead on so I dont think injectors, fuel pump, or fuel pressure is the issue. I don't hear any exhaust leaks before the wide band either.
