Has anyone run into this before, and what can I look at to diagnose the issue?
When I start the vehicle, it idles fine and WB02 readings are within 1% of commanded EQR - but as the vehicle continues to idle, the WB02 reading gets richer, and richer, and richer like it is loading-up with fuel.
Does this mean my injector small pulse adjust table is wrong? The alternator voltage never changed the whole time, so I don't think the Injector Voltage Correction table is involved. Maybe injector timing, or timing trim, or ???
Maybe I need to do a RAFIG? I would not think so, because the long-block is bone stock LQ9.
TIA for any ideas/feedback!
