Question about 1999 Land Rover Range Rover
My 4.0SE Rangie is giving out black smoke and engine is running unsteadily. Initially, the local Land Rover agent has dignosed a defective ECM but replacement n recalibration does not help. Then ignition cables were replaced but within 3 weeks the problem is back again and they cant really determine what wrong with it. Appreciate if you could share your experience and knowledge on solving the problem.
Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor. How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found. I hope this helps you determine what could be causing your engine smoke

Dear sir, black smoke is mainly due to poor "rings" in engine which cannot be repaired by us but u need to take it to the garage to get it done..

Check the catalytic converter as it may be plugged. When a converter is plugged, the pressure in the exhaust system builds up to the point that the intake vacuum drops. This causes the mass airflow sensor to think there is a problem in the engine and set a code.
