When you saw 100% injector duty before, was it "Injector Duty Cycle" or "Fuel Pump Duty"?
Injector duty cycle, i only got it on one log like that, the previous log and the log after peaked around 84 if i remember, but all logs showed afr in the 20s
Did the plugs and packs last week, the plugs were really white, also replaced the rear o2.
Did you get a look at the car today?
