[D-4D] increased fuel consumption and black smoke - Toyota Yaris Forums

When black smoke, lag off power, poor throttle response - Tjeck/clean or replace your EGR valve. this is the first step is this case (how i understand your problems)

Carbon builds up over time, sometimes the valves get stuck or do not FULLY close when you put the pedal to the metal ;-)
The fully close thing is very importent and WILL give black smoke/lag off power....
