SOURCE: high fuel consumption

The fuel pressure regulator or the Mass Airflow sensor are common problems with the 240, and will cause these symptoms.

SOURCE: excessive consumption of fuel of daewoo matiz and cutting off

Sounds like the Oxygen sensor in the exhaust may not be working effectively. Check the connections and wiring running to it. The Oxygen sensor only starts to work when hot so be careful. The sensor outputs a pulse of voltage when the engine is running. If the voltage output is steady then it needs replacing.

Twin turbo 80 horse power deutz Diesel engine blows black smoke under load


Diesel engines smoke when under a heavy load. Unlike a gas engines, a diesel engine uses fuel that is more like an oil.Smoking is a good indication the fuel is not completly burning because of loaded engine spee. White smoke indicates the fuel is not ignitingefficiently. Truck, boats, tanks abd anything else using diesel fuel will smoke when it gets more fuel than it can use.. Easing up on the throttle will lessen the smoke but not eliminate.. Of coarse if the demand is lessened by applying less loadyhe fuel consumption drops.Not to worry as long as the smoke doesn't attract the EPA.

Occasional heavy smoke on tickover, but not using oil and oil clean.


HI do you now the color of the smoke
if engine emits white smoke its not burning the fuel
it could be water mixing with fuel = head gasket even tho you
dot have water in the oil
if engine emits black smoke - that's excessive fuel to air ration
check air filter & air inlet to see if clogged

if engine emits blue smoke - excessive oil consumption
cloud be valve seals

Car hard starts and rough idles and cuts off when attempting to accelerate this is a1989 230e model, it produces a black smoke


Black smoke is burning oil, blue is unburnt fuel. If you are burning oil sound like valve seals in the head are failing.

Smoke coming from exhaust at higher speeds or when putting foot down, also acceleration jerky like am blipping the accelerator not cruising used to cruise 110 no bother now its taking it to reach 100


If the smoke is blue, it is burning oil. If it is black or dark grey it is running way too rich, like your choke is stuck on. That would also explaing the jerky acceleration and poor response. Your fuel consumption will also skyrocket.

I have a 1990 hyundai excel which is burning oil and blowing smoke it is fuel injected


dear friend-if the colour of the smoke is blue then it is oil related and you will see it in the oil consumption,if the smoke is black then it is fuel related,and you will see that in the preformance and fuel consumption,the car will appear to be sluggish.remove the breather pipe and see if oil is dripping from it,if it does then you have a lot of blowby meaning you have to replace the rings.
