2002 Citroen C1

Engine Performance problem
2002 Citroen C1 4 cyl Front Wheel Drive Automatic 15000 miles

When I hit the gas it slowly increases the speed and when I climb a slope it beepes and sometimes at 1st gear I increase the speed to 9mph it shifts to 2nd gear. What could it be, please I cannot take to live slow.

Have the vehicle plugged into a diagnostic computer to locate the cause of the fault !
