A backfiring or smoking exhaust can indicate either too much fuel or too little spark, both of which can bring about power loss. A backfire occurs when the fuel-air mixture does not fully ignite in the combustion chamber, but instead pops off elsewhere in the system.
Why is my car smoking and not accelerating?
When this happens, this can be the result of many things such as faulty fuel injectors, a failing mass air flow sensor or a faulty fuel pressure regulator allowing too much fuel to be supplied to the combustion chamber to be burnt.

Converter can get clogged up over time from rich air fuel mixtures uh you know having the engine cold things like that exhaust particulates can build up in there.
Why is my car losing power and smoking?
Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.
What causes loss of power and black smoke?
Black smoke indicates that the fuel is not burned properly. The internal combustion process in diesel cars requires a certain mixture of fuel and air. The ratio of fuel and air should be proper, otherwise, the mixture will be too rich, which will result in black smoke. Faulty injectors.
Why is my car losing power when I accelerate?
The most common reason a car is losing power when accelerating is due to a clogged fuel filter or engine air filter. It can also be caused by a damaged sensor disturbing the air-fuel mixture like the MAF sensor or O2 sensor.

Most common causes of black smoke are faulty injectors, a faulty injector pump, a bad air filter (causing not enough oxygen to be supplied), a bad EGR valve (causing the valves to clog) or even a bad turbocharger.
Can bad spark plugs cause black smoke?
Check the ring, spark plug, oil seals, valve, gasket, and air filter if your engine is blowing blue or black smoke from the exhaust. Although this is a rare symptom, following our repair guide will help you find the most appropriate part to replace.
Can a dirty fuel filter cause black smoke?
Dirty air-filters that do not allow sufficient air (oxidant) into the combustion chamber for complete combustion of the fuel charge contribute to black smoke.
Why is my car blowing black smoke when I accelerate?
Billowing black smoke is generally a sign that the fuel-air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren’t letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter.
What does GREY smoke mean?
Grey smoke can indicate that the fire is slowing down and running out of materials to burn.
What causes lack of power in a diesel engine?
When a diesel engine is hot, the fuel is used to heat it rather than power it, so it loses power. This can be caused by a variety of problems, including clogged fuel filters, exhaust pipes, dirty air filters, or damaged spark plugs.
Can bad injectors cause loss of power?
A faulty fuel injector can cause the vehicle to experience misfires, a loss in power and acceleration, a reduction in fuel efficiency, and in severe cases can cause stalling or prevent the engine from running at all.
