How many miles are on the car it self? Have you ever had the carbon cleaned off the valves yet? The way these things self tune/learn this stuff can be hard to lock down some times. Are you getting a DAM drop at all? Any Knock or knock learning? Do you always buy your fuel from the same place?
If you have a DAM drop get fuel from a different station and add 1 gallon of E85 to it if you can get it. See if that helps. If it does then you know it’s as simple as fuel quality issue. I used to buy fuel from a local place and all the sudden about 6 months ago I was having odd issues. Started keeping my Accessport in the car and saw DAM drops. I switched stations and it all went back to normal. I don’t know what they but they changed something when they went to a “Top Tier Fuel” verified station.
You can also reload your tune. A lot people say don’t do this. Some say do it. See if the self learning has gone a little out of Wack.
