i own a jdm altezza rs200 z-edition 2001 release with the 3sge 6mt.
at the moment whenever i start it up the revs bounce all in its own. when engine is warmed up the revs rest at a high 2000rpm instead if her normal 750~800rpm and that's if the revs aren't bouncing.
And the weird thing is now dash warning lights are showing. i even took it to a buddy who has an OBD2 machine to read any codes but got nothing.
This begun after i got a jump start after the battery went down.
i have changed battery and even used carb cleaner to clean throttle body and still the issue persists
here is a vid of the revs bouncinghttps://www.youtube.com/watch?v=YNKhvRub84A
any assistance will be highly appreciated
