Sup,

Just got around driving my car a bit, it's been good in the ltft city driving in the past week, but it always had a buzzed up fuel cell (Low Load condition one, when barely pressing on the gas, let's call it LLC).

First Question : What might cause the LLC cell to crawl to 16.4, when, trigering it by lightly pressing the gas, let say, on highway, going down slight slope, or city driving when trying to keep a steady pace.
Second Question : Today something creeped me out, because it never did it, when letting go on the gas in D, it would jump to 16.4, then when giving it gas it would go back into normal -3.9%.
Then when in Park, it would get steady at -3.9%.

Other infos, vacuum was apparently at 20.5in/hg in park, which sounds fine by me, had my car checked for leaks in the past already, gonna re-check it later this week with my mech. All vac lines are new, MAP is new, and stuff.
