    Did some logging on a left turn (3rd event). Anything here look suspicious? Anything else I can log?

      You can see the timing go crazy just after you hit the throttle.

      Couple other things might be RPM. See if at a different rpm if the reading safe different. Fuel trims to see if its dumping extra fuel suddenly or lacking fuel.

      My questions would be does it react the same in different gears
      Does it respond the same in sport mode vs normal mode
      And does it respond the same with all the nannies off vs on

      sent from my galaxy s3. that would explain the errors.

        I've got the RPM's logged, too. Just need to spend more time on the graph.

        It's always the same situation: Entering a left-hand turn and then need a bit more acceleration for whatever reason.

        I only drive in Sport mode.

          That very strange.

          Sounds like has to do with the way a plug or fitting is that its either getting too much or not enough gas.

          Do you have a wideband? Maybe track AFR and see what that looks like.

            No wideband. May need to get one if I have to for this.

            Here is with RPM...

              yeah it all makes sense, as soon as your timing changes your RPM drops, so that would mean lacking either air or fuel. Air wont necessarily change by turning in one direction or another. So that leads me to believe some sort of fueling issue.

              unless like stated in the TSB that its a connector or wire and the inertia from the turn is moving something just enough to lose connection.

              but this is truly a puzzling one for sure.

                I've also had a few misfire codes fly, but, have read that the knock sensors are really sensitive.

                  do you see an increase in knock when turning?
