Hi friends

i have recently bought a ford mondeo 2004 lx 35,000 miles covered... 6 services at regular intervals.....
i found this car awesome and bought it .. but now i have observed that initial power in this car is not good..... the pickup isnt fast and it drives heavy in slow speeds....
also when i reverse ... there is a lotta white smoke initially ..

can someone guide me as to what might be wrong ?

Thanks !!
