i tried to reset the ecu bt removing the battery connectors.. sa 1st start ko okey siya pero once na ioff ko and restart.. umiilaw ulit.. do i need to bring this to casa for the reading? or change it back to stock na lng? okey sana sya lumakas ang hatak and gumanda takbo ng car.. pansin ko lng ang idle rpm ko is nasa 600-700.. is that okey?
