My fault for not giving it long enough to adjust , checked exhaust and all intake no leaks. Went for a drive got it up to temp yesterday and long term fuel trims dropped. Back under 10% at all engine loads and idle. Another compression test on the warmed engine and 180 across all 4 cylinders. Thinking Injector seal was the culprit. IMG_3920.jpeg
