I repeated the experiment Scanner-Danner did.
As u can see LTFT step by step increases with time irrespective of RPM – RPM went from around 750 to 1500 to 2500.
As I said before, LTFT comes down when I drive normally. Around city LTFT settles at 12.5. So this does not readily support vacuum leak as supported by Scanner-Danner. If u click the link below image opens on a new page. Some sort of sensors malfunctioning?
