Bro,, i'm a new member for mazda lantis...
my mazda lantis 1.6 (m) only can go araound 40 km for rm10, how can i do to get 60km for rm10? change engine , make diagno..or install any accessory?
and my lantis no pickup (lembap)
zizou,
check ur spark plugs. if it is black full with carbon, meaning ur lantis air/fuel ratio is too rich. check what spark plugs are u using? tell us the feedbacks.
ur O2 sensor might be faulty too...just tell us 1st what's the colour of the plugs & what plugs are u using.
