Why does my car have black smoke coming out of the exhaust?
Black Smoke. Black smoke coming out of your car probably means that the engine is getting either too much fuel or too little oil. For cars with carburettors (i.e non-fuel-injection cars), it might be to do with a problem with the fuel supply (more specifically a defective fuel pump, problem with the purity of the fuel, or a blocked fuel filter).
What causes blue smoke to come out of engine?
Intermittent blue smoke can be caused by a combination of factors, but most frequently it is caused by worn valve seats – a critical part of the engine. This used to happen most often on older cars built to run on leaded fuel, but which are using unleaded instead.
Can a bad catalytic converter cause black smoke?
Yes, a bad catalytic converter can cause black smoke. This happens when your car engine is burning oil too much or from a clog caused by fluids from the engine coolant.

Why is there smoke coming out of my diesel engine?

Why do I have black smoke coming from my tailpipe?
If there is a lack of of air coming into the engine, the fuel will be burnt partially then leads to black smoke from tailpipe. Fuel needs to be burnt fully as it will only emit CO2 and water, which do not cause black smoke. That is why the correct combination of fuel and air is so important if you want to avoid black smoke.

Why does my Trafic engine not Rev properly?
As engines run on fuel mixed with air, you can see that if the MAF is faulty or dirty and giving an incorrect reading, it can have a pretty major effect on how the engine runs. The most common complaint with these vans seems to be that they sometimes are low on power—especially below 2500 RPM—and sometimes won’t rev properly.
Is there a problem with acceleration on a Renault?
Before the Turbo Boost sensor was replaced, the engine would not rev beyond 2000rpm, and was having a hell of a time. I have not noticed any clouds of black smoke under acceleration, so would it be safe to assume that the next best place for the garage to look would be the air flow meter?
