when driving and i put my foot down, the car gets to about 2300rpm and it starts to smoke black out the exhaust, its not clouds and clouds but it is noticeable.
what would cause this? its a 1.9CDTI energy estate, have cleaned the boost sensor, done the airbox mod, new air, fuel and oil filters, and had a set of glow plugs all last week.
if i cruise along normally its fine no smoke, but as soon as a put my foot flat down (overtaking, going up hills etc etc) the black smoke starts to pour out.
please can you help?
