then today i realize that my battery soon died.. the battery have color wan.. green, black and white spot??
so i go change today, ok fine.. RM 180 gone jsut for the battery, then when i take back my car, i start engine... 1500 then wait drop to 800, ok nvrmd i go back home.. then i realize that.. hmm.. normally, i am a light footed driver.. max rpm to my home from my dad shop is 2000 for speed before 70km/h.. [1 gear 2000 2gear 2000 3 gear 2000 4 gear 2000 or below.. that is normally i drive..]
after changing the battery, 1 gear 2000 2 gear 2600+- then 3 gear 2500, 4 gear 3000.. why like that... ?? i dunno wat happen..
