Problem with Renault Scenic Megane?

Question:
I have the above car (02 Reg) It's very sluggish and won't go more than 5 miles an hour. Sometimes its ok, but when playing up, there is loads of black smoke coming from the exhaust. Can anybody tell me what I may need to look at? PLEASE!

YOU NEED TO TELL US IF ITS PETROL OR DIESEL,MAKES A LOT OF DIFFERENCE.
thanks diesel, it sounds like its jumped a tooth on the timing belt,if not it could be the injector pump,quite expensive.look at the timing belt first to see if its slack or any signs of missing teeth.if all looks ok a fitter will have to check the pump out, you havent filled it with petrol by mistake have you ?

How do I make my wheel covers fit?

If it a petrol engine in it the symptoms are of an excessively rich mixture that is too much fuel and not enough air first see if removing the air filter element helps ( this holds good for Diesel engines too ) you can run without the filter for a while but do get it replaced ASAP

What does the "service engine soon" light mean?

maff sensor, its an airflow sensor between the airfilter and the inlet manifold, cleaning doesnt really work so just replace. You can try tapping it when the fault occurs and if the car runs ok at least you know its definately that. Ignore some of the sunday morning specialists on here, if it was timing / pump / air filter, it would do it all the time
