So far the issue has yet to come back... BUT unfortunately the driving conditions are also different so it's not exactly apples to apples. When I was having the issue the days were 100+ degrees, and now since doing the work they are 75-85 degrees.. so that might have an affect on my testing unfortunately.

Keep us posted on your results with the dealer I am very curious.

I've done similar cleaning, the only thing I haven't done yet is the throttle body relearn/calibrations

From what I've researched the ECU will pull timing if the oil temps start getting above 200 degrees, and/or the intake air temps get too high (not sure about the limit on that), however I have an oil cooler and cold air intakes, so I doubt that's it.

I should add that mine is also an '09

I'll keep you guys updated after the appointment....unless I forget
