I have changed my MAF sensor twice in one week and its still went bad. The car emmites black smoke,consumes a lot of fuel,engine jecks while driving, check engine light is on. Each time I change the MAF sensor with a good one,the black smoke stops but after 48 hours it will emmit serious black smoke. Please help me

So, maybe the MAF isn't your problem. Your engine could be getting an over rich mixture from numerous ways. Someone needs to analyze the sensor data with a professional scan tool to determine what is going on in the system.
You could have injectors leaking, a bad fuel pressure regulator or numerous other issues.
