car jerking recently

[sengot]

hi there,
My car's waterpump broke d, eat the belting also. So go change waterpump and a new belting. Just after repair, i go back with the car and its jerking when accelerating (not so hard, but noticeable) and still jerking until now. so i suspect sumthing wrong due to recent changes. Any idea eh ppl?

p/s: driving ek 1.6 sohc no tec one :D
